Abstract

Transparent Zn_0.97La_0.03O nanostructures were prepared at different temperatures (300 °C–500 °C) on borosilicate glass substrates using the chemical spray method. The present work focused on the dependence of the substrate temperature (T_s) on the different characteristics of the prepared films. In all the deposits, a polycrystalline structure of La³⁺ doped ZnO (LZO) film with a preferred orientation along the (101) plane was observed, and a larger crystalline size was noticed for films deposited at lower temperatures. The surface morphology changed from spherical to fibrous structure as a function of the temperature of the substrate. The chemical state and elemental compositions were confirmed by XPS analysis. The linear optical band gap and third-order nonlinear absorption coefficient of LZO films were observed to increase with an increase in substrate temperature. A maximum transmittance was observed for the sample prepared at 450 °C with the least optical limiting threshold value of 0.96 kJ/cm². The presence of various defects in the film was confirmed through photoluminescence emission, and red emission was noticed for samples prepared at 450 °C and 500 °C.
