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.
