Abstract
We investigated the formation behavior of ternary rare earth sulfide LnxGd2-xS3 (Ln: La, Tb). Ternary rare earth sulfide LnxGd2-xS3 (Ln: La, Tb) was synthesized via the sulfurization of their commercial oxide powders using CS2 gas for short sulfurization time. It was found that ternary rare earth sulfide LnxGd2-xS3 (Ln: La, Tb) could be synthesized for a short sulfurization time of 3 h at 1100°C. For LaxGd2-xS3, it crystallizes in α phase (Orthorhombic phase), the crystal structure is different from rare earth sulfide La10S14-xOx which crystallizes in β phase (Tetragonal phase) but is same with rare earth sulfide α-Gd2S3. TbxGd2-xS3 also crystallizes in α phase, the crystal structure is same with rare earth sulfide α-Tb2S3.
