Abstract

We present in this work some results concerning the effects of the thermal annealing with CdCl₂ on the optical properties of CdS thin films grown by radio-frequency planar magnetron sputtering technique, under optimized growth parameters: gas pressure, atmosphere, substrate temperature, power of plasma, etc. An improvement of the optical properties has been observed, mainly the presence of radiative emission (luminescence) at room temperature. This fact allowed us to carry out a deep study of the photoluminescence (PL) properties of the CdS films, in the range of temperature 10≤ T ≤ 300 K. Radiative emission at the high energy side has been observed and related to exitonic processes. Temperature quenching experiments gave rise to the calculation of the activation energies for each one of the radiative emissions (PL bands).
