Influence of reaction parameters on crystal phase growth and optical properties of ultrasonic assisted hydro- and solvothermal synthesized sub-micrometer-sized CdS spheres

Sub-micrometer-sized CdS spheres were synthesized by hydrothermal and solvothermal reactions using Cd(NO3)2.4H2O and CH4N2S raw materials at a constant stoichiometric 1 : 2, Cd : S molar ratio. Various conditions such as solvent type (water and/or ethanol), reaction time and temperature were examined for the synthesis of the targets. The sy...
