Chromaticity-Tunable and Thermal Stable Phosphor-in-Glass Inorganic Color Converter for High Power Warm w-LEDs.

ABSTRACT: In this work, an aluminate silicate garnet phosphor, Y₂Mg₂Al₂Si₂O₁₂:Ce³⁺ (YMASG:Ce³⁺), exhibiting strong and broad yellow-orange emission, was successfully synthesized. Attributed to the double cation substitution of YAG:Ce³⁺, which led to a compression effect, a redshift was observed with respect to YAG:Ce³⁺. More importantly, a transparent phosphor-in-glass (PiG) sample was obtained by incorporating the phosphor YMASG:Ce³⁺ into a special low-melting precursor glass. The energy dispersive spectrometer (EDS) mapping analysis of the as-prepared PiG sample indicates that YMASG:Ce³⁺ was successfully incorporated into the glass host, and its powders were uniformly distributed in glass.
