Nanostructures of lead doped zinc oxide: Synthesis and characterization

Lead doped ZnO nanocrystallites have been synthesized in the laboratory using low temperature chemical precipitation technique. Precursor was prepared using absolute ethanol, zinc acetate and lead acetate in fixed proportions. Precipitates were obtained by adding 0.14 M LiOH into the precursor solution. Scanning electron microscopy images were obtained for studying morphology of the synthesized doped nanophosphors. Photoluminescence in the visible region has been recorded. Owing to increased quantum efficiency, these nanophosphors can be utilized for various industrial applications such as coating materials for fluorescence tubes, optical memories, bio-sensors, active medium for laser oscillations.
