“…Jaśkaniec et al [ 16 ] recently suggested that solvent polarity on the synthesis method is strongly related to these 2D morphology changes. As an example, SnO can be obtained as platelets [ 8 , 17 ], rose-like particles [ 13 , 25 , 26 ], and other hierarchical architectures [ 9 , 10 ]. In our case, both plates and nanoparticles morphologies were formed via hydrolysis.…”

“…However, its use is still under-explored due to limitations concerning its synthesis in a pristine form without other Sn-based oxides and its easy oxidation to SnO 2 . Different synthesis routes have been employed up to now for the synthesis of SnO nanoparticles, such as the hydrothermal method [ 7 , 10 , 13 ] and microwave-assisted synthesis [ 14 ], whereas other methods such co-precipitation and hydrolysis remain less explored so far.…”

In this work, semiconductor tin oxide (II) (SnO) nanoparticles and plates were synthesized at room conditions via a hydrolysis procedure. X-ray diffraction (XRD) and transmission electron microscopy (TEM) confirmed the high crystallinity of the as-synthesized romarchite SnO nanoparticles with dimensions ranging from 5 to 16 nm. The stability of the initial SnO and the controlled oxidation to SnO2 was studied based on either thermal treatments or controlled laser irradiation using a UV and a red laser in a confocal microscope. Thermal treatments induced the oxidation from SnO to SnO2 without formation of intermediate SnOx, as confirmed by thermodiffraction measurements, while by using UV or red laser irradiation the transition from SnO to SnO2 was controlled, assisted by formation of intermediate Sn3O4, as confirmed by Raman spectroscopy. Photoluminescence and Raman spectroscopy as a function of the laser excitation source, the laser power density, and the irradiation duration were analyzed in order to gain insights in the formation of SnO2 from SnO. Finally, a tailored spatial SnO/SnO2 micropatterning was achieved by controlled laser irradiation with potential applicability in optoelectronics and sensing devices.

“…It is comparable to the previous research by Huda et al in which it was reported that the peak of the absorbance spectra of SnO 2 thin oxide is in the 250300 nm ultraviolet (UV) range. 22) Unfortunately, the absorbance in this research was only observed in the visible range. In this study, contrary to the percentage of transmittance, the sample at the annealing temperature of 1000°C has the highest absorbance peak at about 2 in the UV range (Fig.…”

A 250 nm thick pure tin film was deposited on quartz substrates by vacuum evaporation of 99.9% pure tin metal. The films were heated in a two-step annealing sequence for 3 h at 200 and 3 h at 400°C with an electric furnace to decrease their surface roughness. This process transformed the films into tin(II) oxide. Subsequently, the films were annealed at five temperatures for 3 h each: 600, 700, 800, 900 and 1000°C. The crystal structure of the film on the quartz substrate was completely transformed into SnO 2 at 600°C. With the increase of annealing temperature to 1000°C, the size of the lattices appeared to decrease on the thin film. In addition, the annealing process led to the formation of pores on the surface, but the number of pores and the lattices volume decreased with increased annealing temperature. The optical properties of the thin film were characterized by the use of visible spectrophotometry which showed a high refractive index at around 2.082.27. Interestingly, the SnO 2 thin film with the highest refractive index at 2.27, which was obtained at 1000°C, exhibited the lowest Urbach energy. Therefore, the SnO 2 thin film has a high potential for optical applications, especially in dielectric waveguides and solar cells.

“…The absorption edge shift and the bandgap increase were observed at the increase of pressure or substrate temperature. The polycrystalline SnO film synthesis with the conversion to the SnO 2 phase at the growth temperature increase from 400 to 700°C was reported in [25]. The change of absorption and bandgap at the temperature increase is considered in the same article.…”

Nanostructured SnO(x) films were obtained by molecular beam epitaxy (MBE). The morphology, structure, and optical properties of obtained films annealed in the temperature range of 200°C-1000°C were studied. The reflection high-energy electron diffraction during the film deposition by the MBE method and the x-ray phase analysis showed that the initial films are in the polycrystalline phase. A single orthorhombic SnO 2 phase was obtained for the first time after annealing the SnO(x) film in the air at a temperature of about 500°C. The sharp change in the optical constants near the temperature of 500°C was established using ellipsometry. The pronounced absorption edge appears in the short-wave region at temperatures above 500°C and it disappears at lower temperatures. The film thickness changed non-monotonically during the annealing in the air. At first, it grows from 45 nm to 65 nm (active oxidation to 500°C), and then (above 600°C) it begins to decrease. The annealing at temperatures of 500°C-1000°C leads to the film compaction, since the film thickness decreases to 50 nm, but the refractive index increases by 10%-15%. Optical constants track the progress of film phase and morphological changes.
