Abstract

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 ⁶⁰Co and their thermoluminescence properties were also investigated.
