This paper demonstrates the synthesis of SnO 2 nanoparticles using a simple hydrothermal route in the presence of the surfactant hydrazine at 100°C for 12 h. X-ray diffraction (XRD), field emission scanning electron microscopy, and transmission electron microscopy (TEM) were employed to characterize the as-prepared product, and optical property was studied by UV-visible diffuse reflectance spectroscopy (DRS). The XRD pattern of the as-prepared sample is indexed to the tetragonal structure of SnO 2 , and the calculated particle size is 22.4 nm, which is further confirmed by TEM. The selected area electron diffraction patterns showed continuous ring patterns without any additional diffraction spots and rings of secondary phases, revealing their crystalline structure. Analysis of the DRS spectrum showed the bandgap of the synthesized SnO 2 to be 3.6 eV. The anionic surfactant hydrazine plays a key role in the formation of the SnO 2 nanostructures. A probable reaction for the formation of SnO 2 nanoparticles is proposed.

Nanostructured CdSnO 3 thin films were prepared by spray pyrolysis technique. The nanostructured CdSnO 3 film showed selectivity for LPG gas over other conventional gases. The maximum LPG response of 1460 for the sample S2 at 350 °C was achieved. The quick response (T Response = 5 s) and fast recovery (T Recovery = 11 s) are the main features of this film. Additionally, the stability of the prepared sensor has been studied. As prepared thin films were studied using XRD, FE-SEM, and EDAX to know crystal structure, surface morphology, and elemental composition, respectively. The results are discussed and interpreted.

Flexible BaTiO 3 films as dielectric materials for high energy density capacitors were deposited on polyethylene terephthalate (PET) substrates by r.f. magnetron sputtering. The growth behavior, microstructure and electrical properties of the flexible BaTiO 3 films were dependent on the sputtering pressure during sputtering. The RMS roughness and crystallite size of the BaTiO 3 increased with increasing sputtering pressure. All BaTiO 3 films had an amorphous structure, regardless of the sputtering pressures, due to the low PET substrate temperature. The composition of films showed an atomic ratio (Ba:Ti:O) of 0.9:1.1:3. The electrical properties of the BaTiO 3 films were affected by the microstructure and roughness. The BaTiO 3 films prepared at 100 mTorr exhibited a dielectric constant of ~80 at 1 kHz and a leakage current of 10 −8 A at 400 kV/cm. Also, films showed polarization of 8 µC/cm 2 at 100 kV/cm and remnant polarization (P r ) of 2 µC/cm 2 . This suggests that sputter deposited flexible BaTiO 3 films are a promising dielectric that can be used in high energy density capacitors owing to their high dielectric constant, low leakage current and stable preparation by sputtering.
