Abstract: Photoluminescence from Cu 2 ZnSnS 4 bulk single crystals was studied as a function of temperature and excitation power density. The bulk single crystals showed a broad luminescence between 1.1 and 1.45 eV. The peak energy of the photoluminescence was shifted to higher energy side when the excitation power density was increased. The origon of the photoluminescence was attributed to donor-acceptor pair recombination with an activation energy of 48 meV.
