Due to their unique scintillation, phosphorescence, magnetic, and catalytic properties, rare earth oxide compounds have recently become one of the most in-demand materials used in different ways. The current study investigated the impact of Ar:O2 gas flow variation on the deposition of La2O3-doped zinc oxide thin films (TFs) on silicon dioxide (SiO2) substrates using the radio frequency sputtering technique. FE-SEM analysis has shown a smooth surface topology and purity of La2O3-doped ZnO TFs. X-ray diffraction analysis exhibited a single-phase hexagonal wurtzite-type structure in TFs. A UV–Vis–IR spectrophotometer examined the optical characteristics of ZnO and La2O3-doped ZnO TFs in 300–800 nm wavelength range. The bandgap of La2O3 doped ZnO TFs changed from 2.9 to 3.1 eV as argon and oxygen concentrations in (Ar:O2) gas flow changed. A variation in optical constants such as dielectric constants, refractive index, and extinction coefficient was observed when ZnO and La2O3-doped ZnO TFs were exposed to variable (Ar:O2) gas flow ratios. The photoluminescence analysis of ZnO and La2O3-doped ZnO TFs was performed at an excitation wavelength of 330 nm. Atomic force microscopy further revealed that La2O3 doping resulted in smoother surfaces and smaller grain sizes. This comprehensive study provides valuable insights into the relationship between doping, gas composition, and the optical and structural properties of ZnO TFs. The obtained results on the optimal flow rate of argon gas provide valuable insights for determining the appropriate deposition conditions of La2O3-doped ZnO TFs, specifically for their application in solar thermal systems.

“…Thin films formed at different substrate temperatures and powers show a rise in the icing time delay, as shown in Table 2. Consistent with what was found in the referenced literature, increasing the surface roughness improved the contact angle [50,51]. Furthermore, differences in temperature and RF power of formed thin films are connected with the composition of chemicals of the coatings when they are developed.…”

The structural, wettability, and optical characteristics of aluminum-doped zinc oxide (AZO) thin films were studied with the objective of understanding the impact of deposition power and deposition temperature. Thin films were deposited using a radio frequency (RF) magnetron sputtering technique. The power output of the RF was augmented from 200 to 260 W, and the temperature was increased from 50 to 200 °C, which led to the development of a (002) peak for zinc oxide. The study of film thickness was carried out using the Swanepoel envelope method from data obtained through the UV-Vis spectrum. An increase in surface roughness value was shown to be connected with fluctuations in temperature as well as increases in deposition power. The findings revealed that as deposition power and temperature increased, the value of optical transmittance decreased, ranging from 70% to 90% based on the deposition parameters within the range of wavelengths that extend from 300 to 800 nm. The wettability properties of the samples were studied, and the maximum contact angle achieved was 110°. A Peltier apparatus was utilised in order to investigate the anti-icing capabilities, which revealed that the icing process was slowed down 3.38-fold. This work extends the understanding of the hydrophobicity and anti-icing capabilities of AZO thin films, specifically increasing both attributes which provide feasible options for purposes requiring resistance to ice.
