CoO-CuO-SiO_2三元系统着色涂层的研究

THE COLORED FILM OF TERTIARY SYSTEM CoO-CuO-SiO_2

利用溶胶-凝胶法制备反射膜、抗反射膜以及着色涂层的研究近年来较引人注目。山本雄二等报道过CoO-SiO_2、CuO-SiO_2、NiO-SiO_2等二元系统着色涂层,涂层的颜色基本上与其中所包含的有色离子颜色相同。本文采用溶胶-凝胶法制备了CoO-CuO-SiO_2着色涂层,得到了具有Co^(2+)和Cu^(2+)的混合颜色的着色涂层,并确定了该体系的成膜区。

The colored film of CoO-CuO-SiO_2 system was prepared by sol-gel method. The effect of several factors, such as concentration of oxides, viscosity of coating solution, heating temperature and heating time on optical transmittance of the film were examined and the compositions for homogeneous glass films were determined. The homogeneous films can be produced only from the system containing more than 50 mol% SiO_2. Both Co^(2+), and Cu^(2+) ions were shown not to take part in network bonds formation.
