Abstract

The thiogallate phosphors which are well known for a long time as phosphor materials for CRT or EL device were reported. Those have high luminescent properties at long-wavelength region. Among those phosphors, the samples with divalent europium doped CaGa₂S₄ were prepared by a simple process under the reduction atmosphere (5% H₂/95% N₂) without toxic gas such as H₂S or CS₂. The prepared phosphor shows a higher luminescent efficiency (about 120%) than that of YAG:Ce³⁺ phosphor. Consequently, this phosphor is possible to be applicable to white LED lamp because of the high luminescent efficiency.
