摘要

In this study, fluorescence characteristics were evaluated by synthesizing Eu2+ doped samples for phosphates of various compositions. The study led to a green light emitting KSrY(PO4)2:Eu2+, which is rare for a phosphate phosphor. KSrY(PO4)2:Eu2+ had an excitation band between 250 and 450 nm and emitted green light, reaching an emission maximum at 520 nm. As this result suggests that excitation by a near-ultraviolet LED is possible, KSrY(PO4)2:Eu2+ could be useful as a phosphor for white LEDs.
