Green Led Light Emitting Diodes

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.

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.

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.

Green Jobs - LED Lighting

LED lighting for your home

More and more people today are looking for ways to go green in their homes, apartments & offices. If you're looking to bring new life to your home living room, bathrooms, kitchen or other areas, consider LED lights in place of traditional bulbs & other home lights. These are a great way to "go green" & do your part for the environment. There's also benefits to your wallet as well as you can reduce costs significantly

Now that energy efficiency in home lighting is becoming more prevalent, we also see improvements in lighting design and an increase in the use of LED lights in home lighting systems. Most of us should be familiar with the typical incandescent light bulb. It's filled with gas as well as a filament stretched across the inside. In traditional bulbs, electricity runs across the filament, it heats up and causes the bulb to glow. Incandescent bulbs create a lot of wasted energy as they produce more heat than light .

A new alternative exists- the LED (light emitting diode) bulb. Led lights give a brighter light, lower energy use & longer lasting bulb.

Another great thing about LED lights is that they now available in a variety of shapes & sizes to fit the lighting fixtures you already have in your home. This makes it easier than ever before to update your home with new, energy efficient, LED lighting. No expensive refitting, just screw in the new bulb and you on your way to a greener, cheaper lifestyle
