Abstract (in Japanese) (See Japanese page) 
(in English) Photoluminescence from Cu2ZnSnS4 (CZTS) thin films and bulk single crystals was studied as a function of excitation power and temperature. The thin films and bulk single crystals showed a broad luminescence between 1.1 and 1.4 eV and between 1.1 and 1.45 eV respectively. The peak photon energy of the photoluminescences was shifted to higher energy side when the excitation power was increased. The origin of the photoluminescences was attributed to donor-acceptor pair recombination with activation energy of 39 and 37 meV for CZTS thin film and bulk single crystal respectively. Transmittance spectra for the thin films were studied as a function of temperature. The band gap energy shift was smaller than 10 meV with increasing temperature from 22 to 300K.
