德国专利:RCA 公司研制的荧光屏是按常规的涂层次序制成的。在前面板玻璃屏上依次涂敷:发光层,金属光反射层和用 SiO_2粒子结合在一起的石墨和或无定形碳粒子的涂层。碳和二氧化硅的重量比是0.9—1.1,可以先在反射层上沉积树脂中间层。在沉积碳粒子之前或之后沉积二氧化硅,也可以在沉积前将碳和二氧化硅混合。硅溶液的蒸发热解可以形成二氧化硅粒子。
German patent: RCA company developed fluorescent screen is made according to the conventional coating order. The front panel glass screen is sequentially coated with a light-emitting layer, a metal light-reflecting layer, and a coating of graphite and / or amorphous carbon particles bonded together with SiO 2 particles. The weight ratio of carbon to silica is from 0.9 to 1.1, and a resin intermediate layer may be deposited on the reflective layer first. Depositing the silica either before or after depositing the carbon particles may also allow the carbon and silica to be mixed prior to deposition. Evaporative pyrolysis of the silicon solution can form silica particles.
