 abstract={CdSe1-xSx (x = 0, 0.3, 0.4, 0.6, and 1) thin films were deposited on a quartz and silicon substrate using high-frequency magnetron sputtering. X-ray diffraction analysis estimated that the CdSe1-xSx thin films are crystallized in a hexagonal structure [structure type – ZnO, space group P63mc (No. 186)]. Spectral dependence of the optical transmittance between 300 and 1500 nm of the obtained thin films at room temperature was measured. Normalized integral optical transmittance, optical band gap, spin-orbit splitting, and the value of the bowing parameter of the CdSe1-xSx thin films are determined. The values of the optical band gaps for CdSe1-xSx thin films were estimated using the two methods (by Tauc plot and dT/dλ). Concentration dependences of the energy gaps connected with the leading optical transitions in CdSe1-xSx (Г8v–Г6c, Г7v–Г6c) and spin-orbit splitting are studied. It is shown that the concentration dependences of main optical transitions are quadratic. The principal explanation for this seems to be the Burstein–Moss effect, which is caused by the doping atoms' excess carriers (electrons and holes).},
