Transparent conducting SnO2 thin films synthesized by nebulized spray pyrolysis technique: Impact of Sb doping on the different physical properties

Nitrocellulose‐Passivated SnO2 Thin Film as a Ultraviolet‐C Photodetector

“…Surprisingly, after surface passivation, the lattice constant c was slightly shifted (3.12 Å) toward the standard, indicating an improvement in crystallinity, as the oxygen end group of the NC chain occupied a portion of the oxygen vacancies. [ 30,31 ] The UV–vis absorbance spectrum recorded on SnO 2 thin films before and after surface passivation (see Figure 1b) demonstrates this, with both films exhibiting comparable behavior, with strong absorption around 317 nm and a slight increase in overall absorption after surface passivation. [ 24,32,33 ] According to a theoretical analysis of the spectra using Tauc's equation, the bandgap of pure SnO 2 thin film is 3.43 eV, which is lower than the standard (3.8 eV) and can be attributed to the presence of oxygen vacancy defects in the film.…”

Visible light activated SnO2:Dy thin films for the photocatalytic degradation of methylene blue

“…The strain was decreased with the increase of Dy to attend 2.44 × 10 −3 rad for the 5% thin film, then an increase was subsequently recorded for layers doped to 7%. 44 …”

Improved optoelectronic properties of Yttrium co-doped CdO:Zn thin films fabricated by nebulizer spray pyrolysis method for TCO applications

“…The other possible reason for decrease in the size of the crystallite size is a change in the preferential growth [38]. Recently, AlFaify and his co-workers [5] and Faruk Hossain et al [39] manufactured optoelectronics materials that showed a similar decrease in crystallite sizes. Moreover, the dislocation, density, and strain value increase with the increase in the concentration of Y.…”
