Effect of hydroxyl concentration on the structural and optical properties of zinc oxide nanoparticles
Issue Date

Abstract
Zinc oxide (ZnO) nanoparticleswere successfully synthesized by chemical precipitation method at different hydroxyl concentrations. The resulting nanoparticles are characterized by transmission electron microscopy (TEM), ultraviolet-visible (UV-VIS) and photoluminescence (PL) spectroscopy. From TEM images, the measured average sizes of the nanoparticles were 4.45 nm to 5.26 nm. Selected area diffraction(SAED) patternsconfirmed that the nanoparticles were of highly crystalline ZnO having wurtzitephase structure.The energy band gap values red-shifted from 3.79 to 3.64 eV based from excitonic absorption peaks. All the samples exhibited a strong visible emission and decreasing peak intensity in increasing OH-concentration.
