Effect of [OH-] linkages on luminescent properties of ZnO nanoparticles
arXiv:1109.1625 · doi:10.1021/jp204504q
Abstract
Optical properties of ZnO nanoparticles prepared from a simple chemical method using sodium zincate bath show strong white light emission. X-ray absorption fine structure studies reveal a completely different local environment around Zn in these ZnO nanoparticles. The observed luminescence properties and local structural changes have been explained on the basis of a linkage between Zn and OH- ions in the surface layers of ZnO nanoparticles.
