A non-vacuum, two-step process has been used to prepare a series of nanocrystalline CuIn1−xGaxSe2 (x = 0, 0.25, 0.5, 0.75, 1) materials. An open-air solvothermal preparation in triethylenetetramine solvent was followed by annealing at 500 °C in a nitrogen atmosphere for 20 min. All materials have mixed clustered plate, spherical particle, and nanorod morphologies with the smallest particle diam...

silver nanowires were synthesized by solvothermal method through reducing silver nitrate (agno3) with ethylene glycol (eg) in the presence of polyvinylpyrrolidone (pvp). in order to prevent the agglomeration of ag+ in the initial ag seeds formation, sodium chloride (nacl) was added into the solution to form agcl colloids. by dissolving agcl in the late stages, ag+ ions were released into the so...

In this study, Bi-doped ZnO and undoped nanomaterials have been synthesized by the solvothermal reaction method. The effect of Bi doping on structural electrochemical properties has investigated X-ray diffractions (XRD), photoelectron spectroscopy (XPS) and, scanning electron microscopy (SEM). As seen from diffraction spectra performed bulk material, it clearly observed that both changed prefer...

The objective of this work was comparing the optical performance hydrothermally and solvothermal synthesized unique florescent carbon quantum dots (FCQDs) from organic material use it as a fluorescent ink for one significant information encryption applications. goji berry sucrose were used source experiment. FCQDs obtained by simple hydrothermal methods using water, isopropanol acetone solvent....
