Combustion Synthesis and Luminescent Properties of Nanocrystalline ZnO

Nanocrystalline ZnO was prepared by the combustion synthesis method for the first time. XRD results show that the samples crystallize in the same structure as bulk ZnO material, with particle size of about 20nm. Fluorescence properties were also investigated. Apart from the intrinsic CV transition peaked at 390 nm, green and red emission bands also appear in the cathodluminescence spectra, and their relative intensity changes with the ratio of fuel and oxidant.
