| As a zinc-based oxide direct band gap semiconductor material, The roomtemperature bandgap of it is3.37eV and Exciton binding energy is60meV. The zincoxide can be widely applied to the short wavelength light emitting diodes, solar cells,and other industries. Large reserves of zinc oxide on Earth, material abundance andlow cost, environment-friendly, sustainable development advantage. And its ownthermal and chemical stability are better. However, the application of zinc oxideneed to solve two major problems: First, the p-type dopant:the second is the energyband structure and optical properties of regulation. Both independent of each otherand support each other.In this paper, the work includes the following two aspects:1. Zinc acetate and potassium hydroxide are used as reaetants, hydrothermalmethod is used to synthesize ZnO nanoparticles. The influence of reaetion conditionssuch as the ethanol content in the reaction solution and the different molar ratios ofSodium thiosulfate in reaction conditions on the morphologies and optical propertiesof nano-ZnO crystal growth was discussed. The X-ray diffraction (XRD), scanningelectron microscopy（SEM）, photoluminescence(PL) test methods are used todescribe the crystal struetures composition, surface topography andphotoluminescence properties. What is more, discussed influence mechanism of themolar ratios of Sodium thiosulfate, ethanol and surfactant CTAB on ZnO crystalgrowth and the optical properties of ZnO nanoparticles.2. Two step anodic method is chosen to by changing the CTAB amount of thesubstance in the aqueous solu, Preparing of high-quality the doped sulfur zinc oxide material. |
