This document summarizes recent developments in LED phosphors for lighting and display applications. It discusses the requirements for phosphors used in LEDs, including spectral response, efficiency, stability, and more. Several commercially available blue and UV-excitable phosphors are described, including garnet phosphors like YAG:Ce, and nitride phosphors like CaAlSiN3:Eu. The document also discusses using phosphor-doped ceramic and resin discs to improve LED performance and consistency compared to traditional silicone encapsulation of phosphors.
