CdGa2Se 4 thin films were prepared by vapour deposition onto either room temperature or preheated quartz and glass substrates (Ts) or they were deposited at room temperature and then annealed at about (TA) 623 K. The films thus prepared were crystalline with a thiogallate tetragonal structure. The o
Reflectivity spectra of CdGa2Se4, CdGa2S4 and CdA12S4 crystals have been investigated in the range 1-6 eV for the polarization E It c and E Z c at 300 and 77 K. The valence band splitting caused by spin-orbital interaction and by crystal field are calculated for the point k = 0. The band model has b
