Structural characterization and photoluminescence properties of zinc oxide nano particles synthesized by chemical route method

Nanostructures, crystalline Zinc oxide powder were synthesized by mixing Zinc chloride (0.04M) and sodium hydroxide (0.08M) using chemical route method. 0.001M molar concentrations of TEA (Tri ethanolamine) in aqueous solution used to the growing reaction solution. The powder samples are annealed at 190 °C. The experimental results indicate a successful growth of Zinc oxide in solid form which is not observed ever before. XRD, SEM, TEM and PL were performed to characterize the morphology, growth and optical nature of the samples. The some Rod and particle like morphology of zinc oxide has been examined by transmission electron microscopy. The particle size was found to vary from 7 to 21 nm. The room temperature PL spectra exhibits low intensity UV emission peak at 407 nm and blue emission band around 484 nm.
