Nickel and cadmium thin films were spray pyrolysed on glass substrates at temperatures between 200°C and 400°C. The impact of these temperatures on the films' growth mechanism and physical characteristics was investigated with a view to their potential use in optical applications. Irrespective of the substrate temperature, the films were characterized as having a polycrystalline structure with a cubic orientation predominantly at the (1 1 1) plane. With higher substrate temperatures, there was a notable increase in film transparency. Furthermore, as the substrate temperature increased, the optical band gap decreased between 3.45 eV and 2.48 eV. The results of the study demonstrated the potential for using these films in modern applications such as solar cells.
