“…The optical absorption and transmission spectra of the MgO nanoparticles revealed a change in the band gap transition as the concentration of SnO 2 is increased, with a higher percentage of dopant, there is a small shift toward the longer wavelength region. The sharp increase in the spectra at the absorption edge demonstrates highly crystalline nanoparticles with few surface defects within the films [26,27] . Transmittance and reflectance were calculated separately, the transmittance spectra of the films are plotted as a function of the wavelength of incident light of all MgO:SnO 2 samples.…”

This study investigates the structural and optical properties of MgO:SnO2 nanoparticles using the Chemical precipitation method, The thin films were deposited by the spin coating technique on glass substrates. X-ray diffraction analysis proved the crystalline structure of prepared thin films, with the peaks corresponding to the (110), (101), (200), (211), and (220) planes, with the tetragonal SnO2 crystal structure, Fourier transforms infrared (FTIR), and scanning electron microscope (SEM) used to characterize the functional groups, shape, and dimensions of synthesized metal oxide nanoparticles. The optical properties of the films were studied by UV-Vis spectroscopy, and the bandgap energy was estimated to be in the range of (3.9 - 3.4 eV). The refractive index and extinction coefficient of the films were also determined, and the results indicated that the films had good transparency in the visible region, The study concludes that MgO:SnO2 thin films obtained by spin coating technique have potential applications in optoelectronics and gas sensors.

In this study, CdS: MgO films were synthesized using the chemical spray pyrolysis method, varying the film thickness. X-ray diffraction (XRD) analysis confirmed the polycrystalline nature of the films, with an observed increase in average crystallite size corresponding to thicker films, and The films' surface morphology indicates an absence of crystal defects such as holes and voids . The investigation of energy gap and optical parameters revealed a dependency on film thickness, with the energy gap shifting from 2.412 eV for a thickness of 150 nm to 2.354 eV for a thickness of 750 nm. Hall effect measurements demonstrated an augmentation in carrier concentration with increasing film thickness. The findings suggest a substantial influence of thickness on the physical properties of CdS: MgO thin films. Notably, thicker films exhibit characteristics that make them promising candidates for application as absorber layers in solar cells. This research provides valuable insights into tailoring the properties of these films for optimal performance in solar energy conversion devices, emphasizing the importance of controlling thickness in achieving desired electronic and optical characteristics.
