Control on the Photoluminescence of ZnO Nanostructures Synthesized by a Reverse Micellar Route

Abstract

ZnO nanostructures with controlable properties were synthesized by a reverse micellar system. The morphology and photoluminescence of ZnO nanostructures can be controlled by changing the the ratio of reaction Zn(NO3)2 and MEA. As the ratio of MEA/ Zn(NO3)2 is low, ZnO nanodots were generated with strong blue emission; as the ratio of MEA/ Zn(NO3)2 is increased, the formation of ZnO nanorods with green emission were synthesized. Since the photoluminescence (PL) properties could be adjusted by varying the nanostructures, these ZnO materials have high potential on different applications, for instance, as fluorescence probes.
