摘要

This investigation entailed the deposition of ZnO: CdO thin films onto glass substrates, utilizing a Nd-YAG laser at a wavelength of 1064 nm, with laser intensities of 800, 900, and 1000 mJ. The structural properties were analyzed using X-ray diffraction of the films (ZnO: CdO), revealing that all samples were polycrystalline, exhibiting a hexagonal structure for ZnO and a cubic structure for CdO. AFM tests showed that the thin films made by the PLD method have a uniformly crystalline surface and grains that are very small, around the nanoscale range. We conducted an analysis of the surface morphology utilizing FE-SEM. All the nanoparticles have been successfully prepared as nanomembranes containing agglomerations of nanoparticles in some areas due to strong attractive forces between them, and the membranes also contain a few pores within their structure. Use check (EDX) to verify the presence of the elements that make up the compound. Optical properties were measured using a UV spectrometer. For the wavelength range (300–1100 nm), it was observed that the absorbance values increased with increasing energy. While the energy gap decreased with increasing energy.
