Abstract

ZnO1xSex (0x0.11) thin films have been grown on sapphire (cAl2O3) substrates at the temperature of 350°C by means of the radio-frequency magnetron sputtering technique. The optical transmission, reflectance, and luminescence spectra at room temperature were analyzed. Using the λ-modulation method gives the possibility to reveal the main features of the energy band structure and the nature of the radiative transitions that cause ultraviolet luminescence.
