“…According to the literature [18], the C-H may result from the adsorption and interaction of atmospheric carbon dioxide with water. The Sn-O and Sn-O-Sn vibrations appeared in the range of 400-700 cm −1 as the result of condensation reaction [17,19]. The peaks at 674 and 636 cm −1 are attributed to the Sn-O-Sn antisymmetric vibrations and the peaks at 558 and 520 cm −1 are attributed to the Sn-O stretching vibrations.…”

“…Among the various semiconductor materials, conducting n-type semiconductor tin oxide (SnO 2 ) is having a wide band gap of Eg = 3.6-3.8 eV [4] at room temperature. This conducting oxide is a well known functional material, which can be operative at low temperature with high sensitivity for applications such as gas sensors, transparent conducting electrode, transistor, solar cells, special coating for energy-conversion, low-emissivity windows, and nanoelectronic devices [5][6][7]. Thus, a great deal of research work has been devoted to the method of synthesizing SnO 2 particles of nano sizes in a controllable manner.…”

“…In the present context, it is challenging to overcome the above drawbacks through a controlled chemical precipitation method. Zhijie Li [7] recently reported the room temperature photoluminescence of blue emission with weak intensity. Few reports have been published on the luminescent characteristic of SnO 2 nanocrystalline powder by chemical methods.…”

Nanocrystalline tin oxide (SnO 2 ) powders have been synthesized by a low temperature chemical precipitation method. As-prepared and heated powders were characterized by XRD, SEM and luminescence studies. Crystallographic parameters such as crystallite size, lattice parameters and dislocation density in SnO 2 nanocrystalline powders were calculated by Rietveld analysis. The average crystallite size of 9 -43 nm was obtained for SnO 2 powders through controlled heat treatment process. The washed powders morphology was almost spherical in shape and average agglomerate crystal size was between 0.2 -0.4 μm. A Photoluminescence (PL) study was measured at an excitation wavelength of 265 nm for as-prepared and annealed powders; it showed a broad emission peak at 417 nm for all powders. The highest PL emission was attained for the powder annealed at 500℃. The synthesized nanocrystalline SnO 2 oxide semiconductor material could be suitable for making optoelectronic and sensor devices.
