Effect of Mn low concentration on the optical properties of ZnO nanocrystals

ZnO and ZnO:Mn nanocrystals synthesized via reverse micelle method. The size, band gap, Urbach energy, optical constants and penetration depth of nanocrystals were calculated by UV-vis spectroscopy data. The surface morphology was studied with the use of scanning electron microscope (SEM). Moreover the samples exposed to Gama ray source of ۶۰Co and their thermoluminescence properties were also investigated.
