Effect of solution molarity on properties of hydrothermally grown ZnO nanostructures
2017
In this work, the hydrothermally grown ZnO nanostructures were successfully prepared on indium tin oxide glass using different aqueous solution molarities. The effect of solution molarity on the structual and optical properties of ZnO nanostructures were studied by X-ray diffraction and temperature-dependent photoluminescence (PL) measurements. The PL intensity ratio of the ultraviolet emission to the visible emission is also calculated. It is found that the crystal quality and the optical properties are improved by raising the solution molarity, but too higher solution molarity should lead to the disorder of ZnO structures, and deteriorate the crystal quality.
