Investigation of Reaction Conditions on Alcohol-Thermal Synthesis of ZnO Nanoparticles
ZnO nanoparticles because of their interesting properties and various morphologies, has become one of the most attractive nanomaterials for research objectives. Its significant properties has made it applicable in UV-Light emitters, varistors, transparent high power electronics, gas sensors, etc., . Many approaches have been used to obtain ZnO nanoparticles, including: Hydrothermal , Solvothermal , Reverse micelles , Sol-Gel , Sonochemical , and Chemical Bath Deposition , etc. Among these, hydrothermal and alcohol-thermal methods have been extremely investigated. In this paper, buthanol as a solvent is used for synthesis of Zinc oxide at 130°C and 150°C at different reaction periods. Also the effects of different surfactants including: N_Cetyl_N,N,N,_trimethyl ammonium bromide (CTAB), Poly vinyl pyrolidon-K90 (PVP), Poly ethylene glycol-15000 (PEG) on obtained morphologies were investigated extremely. X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used for characterization of nanoparticles.
