Abstract

In this work, the hydrothermally grown ZnO nanostructures were successfully prepared using the aqueous solution of zinc nitride dehydrate (Zn(NO3)2). The effect of solution molarity on the optical and structural properties of ZnO nanostructures were studied by temperature dependent photoluminescence (PL) measurements. The intensity ratio of the ultraviolet emission to the visible emission is calculated. It is found that the calculated results are also dependent on the solution molarity and consistent with the crystal quality of ZnO nanostructures.
