Abstract

Alkali earth selenide phosphor, SrSe:Eu² and Sr _1-xZn_xSe:Eu², was prepared using a solid-state chemical reaction method. The synthesized phosphor displayed a broad excitation band, which is suitable for blue or near UV LED applications and emits green light (563 nm). Zn² substitution for Sr² greatly enhances the green emission of the phosphors. The samples were also excited with various wavelength emitting diodes (410, 425, and 455 nm) to assess their potential use as phosphors for white LED applications. The LED fabricated with the synthesized phosphor produced white light using blue LED with a CIE-1931 coordinate, T _c and R_a of (0.3199, 0.2777) 6499 K and 49.7, respectively.
