Light-Emitting Diodes (Hardcover) $156.75 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. |

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.

Red and Near Infrared Microcavity LightEmitting Diodes $196.21 Lighting is essential to modern society but it accounts for nearly 20 of the electrical energy usage. Thus efforts to increase the conversion efficiencies of light sources are attracting more and more attention. Potential high efficiency light sources are fluorescent lamps or lightemitting diodes (LEDs). Modern LEDs show internal quantum efficiencies of virtually 100 . However, in the case of standard LEDs most of this light is trapped inside the device because of total internal reflection at the interface semiconductorair. Several methods have been developed in order to increase the extraction efficiency. This can be done either by optimizing the device geometry in order to increase the escape cone or by incorporating a resonant structure in order to force the internal emission into the existing escape cone. The latter approach is called microcavity LED (MCLED) or resonant cavity LED (RCLED) and is presented in detail in this work. Novel concepts to further increase the external quantum efficiency are discussed and experimental results are presented.

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.

The Diodes $93.99 High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).
