一、引言ZnS膜是一种重要的光学薄膜,这种薄膜一般采用热蒸发法来获得。但是,用这种方法蒸镀所得的膜层强度很低,不能满足使用的要求。苏联曾对此作过评论,认为用ZnS蒸镀于锗的增透方法,保证不了膜层有高的机械强度,ZnS膜对酸的作用也缺乏最起码的稳定性,在潮湿气氛中存放一段时间,便可发现镀层的剥落。 I. Introduction ZnS film is an important optical film, this film is generally obtained by thermal evaporation method. However, the strength of the film obtained by this method is very low, can not meet the requirements of use. The Soviet Union has commented on this and believes that the method of enhancing the deposition of germanium by ZnS does not guarantee the high mechanical strength of the film. The ZnS film also lacks the minimum stability to acid and stores for a period of time in a damp atmosphere Time, you can find the coating peeling.
