  • Abstract
    Photoluminescence (PL) spectra of ZnAl2S4 crystals with spinel structure were studied under the extrinsic excitation. The PL bands at 0.98 eV and 1.34 eV are suggested to be caused by native defects; while the bands at 1.61 eV and 2.0 eV are associated with the Cr and Mn impurities respectively. Mn2+ intracentral transitions were investigated by the PL excitation spectroscopy
