A study of the nano-structured aggregated tin oxides (SnO2/SnO) and their structural and photoluminescence properties by a hydrothermal method

Study of blueshift of optical band gap in stannic oxide nanosheets by an uncharged surfactant mediated alcohothermal process

“…The broad band between 450 and 790 cm À 1 is attributed to the tin-oxygen (Sn-O) bond in SnO 2 [5,6,9]. The presence of weak peaks at $ 1119 and $ 2990 cm À 1 is attributed to the stretching mode of C-O-C [13]. These absorption peaks must be caused by POEG molecules absorbed on the surface of SnO 2 nanostructures [13].…”

SnO2 nanoparticles synthesized with Citrus aurantifolia and their performance in photocatalysis

“…The obtained FTIR results were satisfactory to differentiate between concentrations based on the difference in signal intensity. Such differentiation was seen through the characteristic stretching band made by the vibrations of the Sn-O-Sn bond of SnO 2 , from 670 to 570 cm −1 ; the characteristic Sn-O-Sn bond is identified at 640 cm −1 [37,38]. While the signals observed in the range of 1720-1250 cm −1 refer to vibrations possibly of the -OH, CO, and CH modes of the organic molecules, present in the C. aurantifolia peel extracts, which are found on the surface of the synthesized nanoparticles, because while increasing the percentage of extract, the absorption bands in that range also increase.…”

Preparation of tin oxide (SnO2) thin films using thermal oxidation

“…The obtained results showed that crystallization of tin oxide started at about 250 o C and the growth continued at higher temperatures as the organics were removed. On the other hand, it was found that nanocrystalline tin oxide powders were formed only after the hydroxyl groups were completely removed at nearly 600 o C. Mixed semiconductor oxide nanostructures of tin dioxide/tin monoxide (SnO 2 /SnO) have been produced using hydrothermal method [10]. The morphological, structural and photoluminescence properties of the fabricated nanostructures were investigated.…”
