ABSTRACT
Due to their low phonon energy, high photoluminescence efficiency, and great chemical and thermal stability, rare-earth doped phosphor materials have drawn interest. Solid-state lighting’s LED phosphor breakthrough has received a lot of attention up to this point. In this chapter, first, we briefly go through a few sample families of LED phosphors. Second, we provide a design technique with a focus on crystal structural concerns in order to find novel phosphors. Next, we examine the findings of extensive research on recent discoveries and structural designs of LED phosphors that serve as examples of the techniques used by researchers, together with designing new phosphors using structural models that already exist. This chapter summarizes the impact on structure–property relationships and recently reported approaches used in crystal chemistry analysis for the development of LED phosphors, including the impact of doping singly, doubly, and triply charged ions into phosphors. Finally, we cover the subjects of active structural analysis and potential future host materials for color conversion and intensity enhancement in LEDs.
