Abstract
Thio-selenide phosphor, SrGa2SeS3:Eu2+, was prepared usingasolid-state chemical reaction method without the addition of toxic gases or other excess materials. The synthesized phosphor displayed a broad excitation band, whichissuitable for blue or NUV LED applications and emits green light (528 nm). The samples were also excited with various wavelength emitting diodes (410 nm, 425 nm, and 455 nm) to assess their potential use as phosphors for white LED applications. The LED fabricated with the synthesized phosphor produced bluish green light using NUV LED with a CIE-1931 coordinate, Tc and Ra of (0.2309, 0.3436), 11732.3 K and 18.2, respectively.
