Abstract
In this paper, the structural and optical properties of Cd x Zn 1− x O films were studied. The films were deposited by pulse laser deposition (PLD). The Cd concentration was changed in the range from x = 0 to 0.2. The structure of the films was characterized by an atom force microscope (AFM) and X-ray diffraction (XRD). The optical band gap of the films was measured by using transmission and photoluminescence (PL) spectra. The exciton recombination dynamics was investigated by means of the time-resolved photoluminescence (TRPL) spectra of the films at 77 K.
