摘要: Single crystals of CuAlS2 doped with Tb were prepared by the iodine vapor transport technique. These showed bright yellow photoluminescence at room temperature when excited 365 nm line a Hg lamp. The spectrum consists broad band 2.0 eV and sharp emission lines 2.278 2.532 which are tentatively assigned to Tb3+ ion.
