Calculation of Structural Parameters and Optical Constants of Size Dependent ZrO2 Nanostructures

Abstract

In this study, structural parameters and optical constants of size dependent zirconium dioxide (ZrO2) nanostructures were calculated. The effect of particle size was investigated on the calculated structural and optical parameters/constants. ZrO2 nanostructures were produced by chemical route. To change the grain size of the ZrO2 nanostructures, different annealing temperatures (450-550 oC) were applied. The x-ray diffraction (XRD), scanning electron microscope (SEM), and ultraviolet/visible region (UV-Vis) spectroscopy measurement results were used to calculate the structural and optical parameters/constants. The results of XRD measurement showed the ZrO2 nanostructures were crystallized in single tetragonal (cubic) ZrO2 phase. SEM results exhibited dense and homogeneous surfaces and enhanced surface grains with increased annealing temperature. The compositional formation of ZrO2 nanostructures were proved by electron dissipated x-ray and mapping analysis. Optical measuremets were strongly changed dependent on the grain size (GS).
