Effect of the carrier gas on morphological, optical and electrical properties of SnO2 nanostructures prepared by vapor transport
The aim of the study was to explore the effects of carrier gas on the properties of SnO2 nanostructures grown by vapor transport method for possible optoelectronic applications. Nanostructures of SnO2 were synthesized via vapor transport method using Ar plus O2 and N2 plus O2 gas mixtures. It was found that the carrier gas (Ar or N2) has great influences ... إقراء المزيد

Morphologies and optical properties of mixed tin oxysulfide produced by evaporation condensation of SnS
The goal of the present study was to use the evaporation-condensation method of SnS to synthesize mixed novel tin oxysulfide nanostructures. Structural, morphological and optical properties of these nanomaterials were investigated. Synthesis was carried out in horizontal tube furnace using Au coated quartz and Si(100) substrates. The substrates were set along 1–25 cm from the centered alumina boat. The deposition ... إقراء المزيد
