The Fundamentals and Applications of Light-Emitting Diodes: The Revolution in the Lighting Industry examines the evolution of LEDs, including a review of the luminescence process and background on solid state lighting. The book emphasizes phosphor-converted LEDs that are based on inorganic phosphors but explores different types of LEDs based on inorganic, organic, quantum dots, perovskite-structured materials, and biomaterials. A detailed description is included about the diverse applications of LEDs in fields such as lighting, displays, horticulture, biomedicine, and digital communication, as well as challenges that must be solved before using LEDs in commercial applications. Traditional light sources are fast being replaced by light-emitting diodes (LEDs). The fourth generation of lighting is completely dominated by LED luminaires. Apart from lighting, LEDs have extended their hold on other fields, such as digital communications, horticulture, medicine, space research, art and culture, display devices, and entertainment. The technological promises offered by LEDs have elevated them as front-runners in the lighting industry. - Presents a concise overview of different types of light-emitting diodes (LEDs) based on inorganic phosphors, organic materials, quantum dots, perovskite-structured materials, and biomaterials - Includes a discussion of current and emerging applications in lighting, communications, horticulture, and medical fields - Addresses fundamentals, luminescence mechanisms, and key optical materials, including synthesis methods

The development of nitride-based light-emitting diodes (LEDs) has led to advancements in high-brightness LED technology for solid-state lighting, handheld electronics, and advanced bioengineering applications. Nitride Semiconductor Light-Emitting Diodes (LEDs) reviews the fabrication, performance, and applications of this technology that encompass the state-of-the-art material and device development, and practical nitride-based LED design considerations. Part one reviews the fabrication of nitride semiconductor LEDs. Chapters cover molecular beam epitaxy (MBE) growth of nitride semiconductors, modern metalorganic chemical vapor deposition (MOCVD) techniques and the growth of nitride-based materials, and gallium nitride (GaN)-on-sapphire and GaN-on-silicon technologies for LEDs. Nanostructured, non-polar and semi-polar nitride-based LEDs, as well as phosphor-coated nitride LEDs, are also discussed. Part two covers the performance of nitride LEDs, including photonic crystal LEDs, surface plasmon enhanced LEDs, color tuneable LEDs, and LEDs based on quantum wells and quantum dots.

Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.
