In the present work, a study on the optical absorption and emission of CdSxse x-1 thin films is reported. The CdSxse x-1 films deposited by chemical bath deposition method show excitonic transitions in optical absorption and photoluminescence (PL) spectral studies at room temperature. The PL emission peaks are related to Ex (A) free exciton and their LO- phonon replica. The effect of impurities like excess cadmium and excess sulfur on the PL emission peaks is also analyzed.
