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 CaGa 2S 4 were prepared by a simple process under the reduction atmosphere (5% H 2/95% N 2) without toxic gas such as H 2S or CS 2. The prepared phosphor shows a higher luminescent efficiency (about 120%) than that of YAG:Ce 3+ phosphor. Consequently, this phosphor is possible to be applicable to white LED lamp because of the high luminescent efficiency.
