Low Temperature Hydrothermal Growth and the Properties of ZnO Nanowall Films

Related Articles

Abstract Unique ZnO nanowall films have been synthesized by control hydrolysis for seeds growing from sol-gel dip-coating process on ITO substrates followed a low temperature hydrothermal treatment.X-ray diffraction(XRD),scanning electron microscopy(SEM),energy dispersive spectroscopy(EDS),In-ferred reaction spectroscopy(FTIR),ultraviolet-visible spectroscopy(UV-Vis) and room temperature photoluminescence(PL) spectrum have been used to characterize the morphology,composition and structures of the films.The results show that the nanowalls are connected to each other with a thickness of about 20—100 nm.The films are composed of ZnO,zinc acetate(ZnAc) and zinc acetate layered hy-droxy salts(Zn-LHS) before sintering,and they completely change to ZnO by pyrogenation of small mol-ecules such as CO2,H2O after treatment at 500 ℃ with the unique structure remaining unchanged.Pho-toluminescence measurements show strong UV emission at 383 nm.The growth mechanism of ZnO nanowall films has been proposed according to crystal growth theory.
