Abstract

Single crystals of Cd(In1-xCrx)2S4 have been made with values of x of 0, 0.05, 0.10, 0.15, 0.20, 0.26, 0.93, and 1.00. Laser Raman spectra of lattice vibrational modes in those samples have been measured at 92K with three different wavelengths of excitation light; 488.0 nm, 514.5 nm, and 632.8 nm. The changes due to mixing are discussed in four spectral aspects: the relative intensity ratios of different vibrational modes, the mode frequencies, the spectral widths and the depolarisation properties.
