METHODS OF SYNTHESIS OXIDE NANOMATERIALS

Abstract

In this paper we studied the methods of synthesizing nanomaterials. Through the hydrothermal synthesis were synthesized zinc oxide nanorods, and a zinc oxide thin films were prepared by sol-gel method. The advantage of the sol-gel method is a high-level homogenization of the initial components. Homogenization was achieved by dissolving the salt and the compound oxide of initial materials. Technology of the sol – gel method compared to traditional synthesis methods films is the simplest. During the experimental work was performed tasks such as processing of technological parameters of producing thin films, the study of their morphological and optical properties, as well as obtaining zinc oxide nanorods by hydrothermal synthesis. Optimal parameters of synthesizing oxide semiconductor nanomaterials have been identified. The research of structural properties, morphology, reflection spectrum of the optical transmission and absorption of the synthesized samples. It was found that the concentration of reagents and synthesis parameters change affects the properties of the obtained samples.
