ABSTRACT
Phosphor-converted white light emitting diodes (pc-WLEDs) are a new type of energy-efficient lighting technology. The scientific community and the general public are so convinced by light-emitting diode (LED) technology that they will support ecologically benign and energy-efficient lighting in the future. Furthermore, LED technology ensures that LEDs are promising candidates for future low-budget lighting schemes. According to the literature, pc-WLEDs are becoming more and more popular in society as a result of their remarkable advantages, including their high luminous efficiency, low power consumption, durability, and environmental friendliness. The production of white light relies heavily on rare-earth triggered phosphors. We have examined a wide range of pc-WLED research articles in this chapter. The main goal of this research is to investigate various inorganic materials that have been synthesized thus far, as well as their characterization and the LEDs manufactured for environmentally friendly lighting applications. We have covered the development of new LED phosphors and the enhancement of existing phosphors’ characteristics in this study. The color-tunable features of rare-earth activated phosphors are thoroughly examined. In this chapter, a variety of color-tunable phosphor materials have been investigated and reviewed. Applications, difficulties, and potential advancements in the field of pc-WLEDs are also covered in this chapter.
