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.
