FACTORS OF AFFECTING SnO_2 FILMS PREPARED BY SOL-GEL METHOD AND THEIR CHARACTERISTICS
影响Sol—gel法制SnO2膜的因素及膜特性

Sn(OC2H5)4 can be selected as one of the precursors that are used to prepare SnO2films. This paper has reported how to control the hydrozed conditions of Sn(OC2H5)4, pH value (53) and viscosity of the hydrolyzed products in order to form sol solution and so on. Process of the Pyrolysis for the hydrolyzed products and characteristics of the films have been also investigated,including selected suitable temperature of the hbat treatment to obtain better SnO2 films and the rate of rising temperaturel di5cussion of the influence of dopants (additives), electronic beam irradiation and the heating temperature of the substrates on electrical parameters of the films- measured the curvingintensity of the optical fibers coated by SnO2 films when the fiber was broken and also analysis of sensitive pecularity of the films for gases.
