Inquisition of reaction parameters on the growth and optical properties of ZnO nanoparticles synthesized via low temperature reaction route
A low temperature reaction route via ultrasonication has been demonstrated for the synthesis of ZnO nanoparticles. It is found that the morphology and photoluminescence has strong dependence on the surfactant, triethanolamine (TEA) and chelating agent, citric acid. Polyvinylpyrrolidine (PVP) is used as a capping agent. X-ray powder diffraction (XRD), transmission electron microscopy (TEM), FTIR, UV-Vis absorption and photoluminescence spectra are used to characterize the as-prepared ZnO nanoparticles.
