The compound ZnGa2S4 is a tetrahedrally coordinated semiconductor which crystallizes in the defect chalcopyrite structure with S4 or D2d space group /I/. Single crystals (of O.lxO.lxO.1 mm size) have been firstly grown by Nitsche et al. 121. Lateron the photoconductivity spectra in these crystals were investigated 131. A wide photoconductivity band with maximum at 3.18 eV (T = 300 K) was observed. However, the luminescent properties of ZnGa2S4 have not been studied up to now. This note is devoted to the investigation of both the photoluminescence (PhL) and PhL excitation spectra as well as of thermal PhL quenching in these crystals. |
