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.

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 Watch - How it Brought a Revolutionary Change in the World of Wrist Watches

Wrist watches are worn and loved by almost everyone. Earlier simple wrist watches were the only option but then there came the revolutionary LED watches. The first LED watch was developed about 40 years ago in 1970 by Hamilton Watch Company and Electro-Data. In simpler terms, a digital watch displays the time in form of numbers unlike the analogue quartz watch that indicates time through its short and long hands. The first digital watch, that had a red light-emitting diode (LED) display, was made in 18 carat gold and priced at $ 2,100. These watches remained out of reach of the common man until Texas Instruments started a mass production of such LED watches.

These watches are primarily known for its digital number display. Some watches also features dot matrix displays. Once these LED watches became popular amongst people, there were many further advancement made to give the users variety of options. In the year 1982, Seiko came up with an in built small television screen in the watch. This became the latest trend with people of all ages craving to own one of those. Thereafter, Casio took the lead by inventing many more such extraordinary and multifarious features that were loved and possessed by many watch collectors such as a digital watch with a thermometer, a watch that could translate a certain number of Japanese words into English language, a scientific calculator watch, and one that could dial a telephone number, to name a few. To add to the list of inventions Casio introduced a digitally operated watch that could allow the user to store their important computer data into their wrist watches.

An LED watch, nowadays, comes with more subtle features to be able to match up with the requirements of a common man. During late 1980s to mid 1990s there was a trend of high technology digital watches which remained restricted to die hard watch fans who loved to collect different kinds of watches and time pieces. This made these watches less popular amongst the general mass. So, to make everyone sport this new fad on their wrists, companies came up with more basic and less expensive models. This gave a chance to all to try one of these. An LED watch has many advantages such as it is environment friendly, has a longer lifetime than other modes of display, easily to maintain and cost effective.

Digital watches are very easily available in the market. These days, almost every manufacturer produces these LED watches. So, it is extremely easy for a person to walk into a store and find one or even check online to get a huge number of options at great prices. An LED Watch not only makes a fashionable style statement due to its funky and colorful display feature but also saves energy. Despite many advances, almost all watches with digital displays are used as timekeeping watches and are easily available at local stores and/or online retail website.
