In present study spray pyrolysis technique was employed to prepare pure and doped CdSnO3 thin films. The spray pyrolyzed thin films were observed to be nanostructured in nature with particle size less than 10 nm and characterized to investigate its structural, microstructural and chemical properties by means of XRD, SEM/EDS, TEM and surface profilometry. Pure and Zn doped CdSnO3 nanostructured ...

Thin films of LaS were prepared by using spray pyrolysis technique at 270 0 C and thickness were varied by changing the concentration of reactant solution. The films were optically characterized and their variations with film thickness were studies. It was found that thickness can be tuned by varying concentration of reactant solution. The band gap was found to vary between 2.35eV to 2.50eV. Th...

Thin films of CuS (covellite) were deposited onto TCO (SnO2:F) glass by Spray Pyrolysis (SP) technique. Aqueous and water:alcohol (ethanol, 1-propanol) solutions of copper(II) chloride and thiourea with different Cu/S molar ratio have been used as precursors. The substrate temperature was varied from 185°C to 285°C. The structural and the morphological characterization of the films has been car...

Spray pyrolysis technique (SPT) and radio-frequency magnetron sputtering (RF-MS) were used to obtain vanadium oxide (VxOy) layers. The surface morphology was visualized using scanning electron microscopy (SEM) atomic force (AFM). Further, t

Cadmium oxide thin films were fabricated on glass substrates by a simplified and low cost spray pyrolysis technique at different substrate temperatures. The X-ray diffraction study showed that irrespective of substrate temperature all the films exhibits a preferential orientation along the (1 1 1) plane. The values of crystallite size were found to be in the range 20.72 – 29.6 nm. The perce...

MoO3 thin films have been prepared by a simple spray pyrolysis technique at substrate temperature 250C. The structure and morphology of thin films are characterized by X-ray powder diffraction (XRD), scanning electron microscopy and UV-vis spectroscopy. The gas sensing properties of MoO3 thin film is studied at gas concentration 400 ppm and working temperature of 100–400 C. It was found that th...

Practical application of aligned carbon nanotubes (ACNTs) would have to be determined by a matter of its economical and large-scale preparation. In this study, neem oil (also named Margoaa oil, extracted from the seeds of the neem--Azadirachta indica) was used as carbon source to fabricate the bundles of ACNTs. ACNTs have been synthesized by spray pyrolysis of neem oil and ferrocene mixture at ...

The olivine structured mixed lithium-transition metal phosphates LiMPO4 (M = Fe, Mn, Co) have attracted tremendous attention of many research teams worldwide as a promising cathode materials for lithium batteries. Among them, lithium manganese phosphate LiMnPO4 is the most promising considering its high theoretical capacity and operating voltage, low cost and environmental safety. Various techn...
