Organic Light Emitting Diodes (Hardcover) $385.4 Addressing the development of the organic light emitting diode (OLED) based on rare-earth and transition-metal complexes—Europium, Terbium, Ruthenium, and Rhenium—this unique perspective explains how these materials can be used to build organic-LEDs, from chemistry synthesis to device operation and the related charge transfer and confinement. Examining how organic materials can be used to build organic-LEDs, the relationship between the chemistry molecule "design," and state-of-the-art and expected pathways, this intelligent report provides intensive experimental results for scientists and engineers working in this new OLED framework, while maintaining a didactic utility for graduation students and teachers studying optoelectronics.

Polymer Light Emitting Diodes Based on Polyfluorenes $138.61 This work is devoted to the study on Polymer Light Emitting Diodes (PLEDs) based on polyfluorenes, a promising class of semiconductive polymers for lightemitting diode applications. It covers theories of PLEDs, literature overview of polyfluorenebased lightemitting diodes, as well as research results by the authors. In this study, several types of PLED devices based on neat polyfluorenes or polyfluorene blends were designed, fabricated, and characterized. The electrical characteristics of two neat polyfluorenes were simulated via using space charge limited current theory for the holeonly case and/or exploiting a commercial software package.

Light-Emitting Diodes (Hardcover) $186.1 Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

Light Emitting Silicon for Microphotonics $380.76 A fascinating insight into the stateoftheart in silicon microphotonics and on what we can expect in the near future. The book presents an overview of the current understanding of getting light from silicon. It concentrates mainly on low dimensional silicon structures, like quantum dots, wires and wells, but covers also alternative approaches like porous silicon and the doping of silicon with rareearths. The emphasis is on the experimental and theoretical achievements concerning the optoelectronic properties of confined silicon structures obtained during recent years. Silicon based photonic crystals are in particular considered. An in depth discussion of the route towards a silicon laser is presented. Author: Ossicini, Stephano/ Ossicini, S./ Pavesi, L.

CarbazoleBased Emitting Compounds $141.79 Carbazole is a heterocyclic tricyclic aromatic organic compound consisting of two sixmembered benzene rings fused on either side of a fivemembered nitrogencontaining ring. A large number of carbazole derivatives have been designed and synthesized and organic electronic devices based on these derivatives such as organic light emitting diodes (OLEDs), have been investigated. The optical and electrical properties of carbazoles are affected by substitution on the 2, 3, 6, 7 and 9Hpositions. Many carbazole derivatives have sufficiently high triplet energy to make them an efficient host where they can serve as red, green, or blue triplet emitters. Highly fluorescent and stable carbazolebased compounds were synthesized and characterized. Substitution of carbazoles at 3 and 6 position by tertbutyl group enhanced the solubility. Suitably susbtituted carbazoles form highly stable fluorescent organic nanoparticles. The emission of these nanoparticles was reversibly switched on/off in the bluegreen and orangered regions from a change in the ratio of the tetrahydrofuran/water system used in their preparation.

LED police lights are imperative accessories for the police

The LED technology is also used in hand held torches used by the police to locate people and scan areas. These hand held LED police lights produce a very powerful light and aid the policemen substantially in their jobs. Besides that, LED technology is being experimented for using like pepper spray or tear gas for temporarily incapacitating and disorienting belligerent people.

LED police lights, flashing in front of a rushing police car, are quite different from the front lights of other motor vehicles. They blink a lot, and coruscate in brilliant colors. If they were not associated with law enforcement agencies as they are, these lights could be easily mistaken for, or could be referred to as, carnival lights. But the way they are used, make the name 'crime deterrent lights' a more suitable tag for LED police lights than the name carnival lights.

LED police lights are the identification tag of an approaching police vehicle, both for justice seekers and law evaders. For the former, the flashing lights are a comfort signal, while for the latter it is a warning signal. Compared to conventional light sources, these LED police lights are more durable, are smaller in size and its energy consumption rate is also low. Its low energy consumption also translates into low CO2 emission.

The word LED of LED police lights is the abbreviation of 'Light Emitting Diodes', which are electronic light sources. Besides being part of police gear, these light sources are used in remote controls, watch dials, and digital clocks. LED lights are of infrared wavelengths, ultraviolet wavelengths, and visible wavelengths and it is this property that gives it the extra luminescence and color variety.

LED police lights are not a part of an approaching police vehicle alone, but that of an approaching policeman on foot or a two-wheeler also, because LED technology is extensively used in police torch lights. The beams of these hand held LED police lights light up larger areas than traditional flashlights and provide brighter light. Besides, some of these lights also have focusing adjustments that allows the beam to be pinpointed to specific areas, which require to be more clearly seen.

While LED police lights are modern policemen's privilege and comfort, LED technology serves a wide category of other people also. Trekkers and hunters make use of these torchlights in their forays, and the technology is used in the tactical equipments of firefighters as well. Law enforcement agencies other than police also make ample use of LED powered tactical lights.

Tests are being conducted for using LED technology in arenas other than LED police lights. A light device known as LED incapacitators is being tested for use in crowd controlling. The device uses bright colors and varying light frequencies to confuse a crowd of people, or ward off an attacker. While LED police lights are already an important part of police gear, the operational field of the technology appears to be steadily widening.
