ABSTRACT: 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.
