	<span lang=\"EN-US\"><span style=\"font-family:Verdana;\">In this study, fluorescence characteristics were
evaluated by synthesizing Eu</span><sup><span style=\"font-family:Verdana;\">2+</span></sup><span style=\"font-family:Verdana;\"> doped samples for phosphates of
various compositions. The study led to a green light emitting KSrY(PO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\">)</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">:Eu</span><sup><span style=\"font-family:Verdana;\">2+</span></sup><span style=\"font-family:Verdana;\">,
which is rare for a phosphate phosphor. KSrY(PO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\">)</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">:Eu</span><sup><span style=\"font-family:Verdana;\">2+</span></sup><span style=\"font-family:Verdana;\"> 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(PO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\">)</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">:Eu</span><sup><span style=\"font-family:Verdana;\">2+</span></sup><span style=\"font-family:Verdana;\"> could be
useful as a phosphor for white LEDs.</span></span>
