“…On the other hand, significant peak shifts could be observed for the ZnO-SnO 2 sample as compared to the pure ZnO, changes that are probably caused by the appearance of heterostructures between the ZnO and SnO 2 . For this sample, the peaks were found at 71, 404, 667, and 580 cm −1 , the last one characteristic for ZnO being in the form of a small shoulder [47,48]. The peak at 667 cm −1 could be associated with the oxygen vacancies of SnO 2 nanocrystal surface defects [55,56].…”

“…Considering this, our current research was focused on the development of ZnO doped with tin dioxide (SnO 2 ), another inorganic material broadly used in photocatalysis due to its photosensitivity, transparency, and chemical stability. SnO 2 has excellent properties, such as chemical and thermal stabilities, and found applications in dye-sensitized solar cells [43], photocatalyst [44], gas sensors [45], and so on [46][47][48]. In this study, the doping of ZnO particles with Sn ions was carried out by a chemical process, and their physicochemical characteristics were thoroughly explored; the purpose of this doping was to make structural modifications and the possibility to use these particles in simulated solar light photodegradation experiments.…”

Zinc oxide and zinc oxide doped with tin oxide (ZnO-SnO2) particles were synthesized and successfully incorporated into a polymeric matrix by the photopolymerization reaction in the presence of Irg819 as the photoinitiator. The obtained samples were investigated by means of XRD, ESEM/EDX, TEM, FTIR, and Raman spectroscopy. The ZnO particles were obtained in the form of rods agglomerated in flower (or star) structures with lengths of 2–4 μm and widths between 30 and 100 nm, while ZnO-SnO2 samples evolved in the form of cubes, with sides of 350 nm. The prepared composite films with ZnO and ZnO-SnO2 particles were tested in the photocatalytic degradation of malachite green (MG) dye. While the ZnO-based composite film showed a fairly high photocatalytic activity, the hybrid film containing ZnO doped with SnO2 displayed 100% photocatalytic activity after only 45 min of irradiation, being among the most efficient photocatalysts known for MG degradation. In addition, the recycling tests demonstrated that this film displayed high stability during the photocatalysis reaction since no decrease in the photocatalytic performance was noticed after the first three cycles, indicating its suitability for dyes removal and wastewater purification.

“…Tin (Sn) can improve the electrical conductivity of the zinc oxide thin film and can be used in the ZnO structure due to the lower radius of the Sn 4+ ion (0.69 Å), compared to the Zn 2+ ion (0.74 Å), that does not change the lattice of the oxide when used at lower percentages of doping [10]. Many authors have tested tin in the zinc oxide structure, OZGÜR, et al (2019) [11] vacuum deposited large crystallites of ZnO thin films doped with Sn; THIRUMOORTHIA and PRAKASH (2019) [10] deposited (1 0 1) oriented tin zinc oxide thin films by spray pyrolysis and XU, et al (2019) [12] increased the surface energy and photocatalytic activity of ZnO thin films by Sn ions doping.…”

Tin Zinc Oxide thin films were deposited on transparent conductive oxide by chemical bath, at percentages of 5, 10 and 15% of tin (Sn) on the zinc oxide (ZnO) structure. All films were thermally treated to improve its crystallinity. The produced films with tin were characterized by x-ray diffraction and optical measurements, such as absorbance, transmittance and reflectance. The x-ray spectrum showed the formation of the ZnO wurtzite and the crystallite size of the films were calculated to be 53.74; 79.59 and 66.38 nm for the photoanodes at 5, 10 and 15% of tin (Sn), respectively, on the zinc oxide structure. The calculated band gap energy of the films revealed that the presence of tin can reduce the band gap energy to about 3.2 eV. Those films were used as photoanodes on dye sensitized solar cells (DSSC) to observe the effects of the tin (Sn) on the photovoltaic activity of the zinc oxide (ZnO) semiconductor. Parameters such as efficiency and short circuit current density were particularly affected by the presence of tin in the composition, with the 5% Sn ZnO film presenting the best results of 7.56 % efficiency and 34.35 mA/cm2, short circuit current density, the other films presented lower values for efficiency, which can be attributed to lower values of short-current density.

In this work, pure Zinc oxide and tin doped Zinc oxide thin films nanoparticles with various volume concentrations of 2, 4, 6, and 8V/V% were prepared by using the sol-gel method. The optical properties were investigated by using UV-Visible spectroscope, and the value exhibits the direct allowed transition. The average of transmittance was around ~(17-23) %in visible region. The optical energy band gap was calculated with wavelength (300-900) nm for pure ZnO and Sn doped ZnO thin films which decreases with increasing concentration from 3.4 eV to 3.1 eV respectively and red shift. The real dielectric(εr) and the imaginary dielectric εiare the same behavior of the refractive index(n) the extinction coefficient (k) respectively. The optical limiting properties were studied by using an SDL laser with a wavelength of 235 nm. ZnO and doping thin films an found efficient as optic limiting and depend on the concentration of the all samples.
