LED Lighting by Malvin Carl Teich Pdf

LED Lighting is a self-contained and introductory-level book featuring a blend of theory and applications that thoroughly covers this important interdisciplinary area. Building on the underlying fields of optics, photonics, and vision science, it comprises four parts. PART I is devoted to fundamentals. The behavior of light is described in terms of rays, waves, and photons. Each of these approaches is best suited to a particular set of applications. The properties of blackbody radiation, thermal light, and incandescent light are derived and explained. The essentials of semiconductor physics are set forth, including the operation of junctions and heterojunctions, quantum wells and quantum dots, and organic and perovskite semiconductors. PART II deals with the generation of light in semiconductors, and details the operation and properties of III-V semiconductor devices (MQWLEDs and μLEDs), quantum-dot devices (QLEDs & WOLEDs), organic semiconductor devices (OLEDs, SMOLEDs, PLEDs, & WOLEDs), and perovskite devices (PeLEDs, PPeLEDs, QPeLEDs, & PeWLEDs). PART III focuses on vision and the perception of color, as well as on colorimetry. It delineates radiometric and photometric quantities as well as efficacy and efficiency measures. It relays the significance of metrics often encountered in LED lighting, including the color rendering index (CRI), color temperature (CT), correlated color temperature (CCT), and chromaticity diagram. PART IV is devoted to LED lighting, focusing on its history and salutary features, and on how this modern form of illumination is deployed. It describes the principal components used in LED lighting, including white phosphor-conversion LEDs, chip-on-board (COB) devices, color-mixing LEDs, hybrid devices, LED filaments, retrofit LED lamps, LED luminaires, and OLED light panels. It concludes with a discussion of smart lighting and connected lighting. Each chapter contains highlighted equations, color-coded figures, practical examples, and reading lists.

Graphene for Transparent Conductors by Qingbin Zheng,Jang-Kyo Kim Pdf

This book provides a systematic presentation of the principles and practices behind the synthesis and functionalization of graphene and grapheme oxide (GO), as well as the fabrication techniques for transparent conductors from these materials. Transparent conductors are used in a wide variety of photoelectronic and photovoltaic devices, such as liquid crystal displays (LCDs), solar cells, optical communication devices, and solid-state lighting. Thin films made from indium tin oxide (ITO) have thus far been the dominant source of transparent conductors, and now account for 50% of indium consumption. However, the price of Indium has increased 1000% in the last 10 years. Graphene, a two-dimensional monolayer of sp2-bonded carbon atoms, has attracted significant interest because of its unique transport properties. Because of their high optical transmittance and electrical conductivity, thin film electrodes made from graphene nanosheets have been considered an ideal candidate to replace expensive ITO films. Graphene for Transparent Conductors offers a systematic presentation of the principles, theories and technical practices behind the structure–property relationship of the thin films, which are the key to the successful development of high-performance transparent conductors. At the same time, the unique perspectives provided in the applications of graphene and GO as transparent conductors will serve as a general guide to the design and fabrication of thin film materials for specific applications.
