Abstract

The invention relates to a method for preparing a zinc sulfide film. The method comprises the following steps that a quartz tube is installed in an evaporation groove; a molybdenum boat is flatly installed above the quartz tube so that the molybdenum boat can be parallel to the quartz tube in the evaporation groove; the molybdenum boat is firmly connected with a positive and negative electrode seat in the evaporation groove; zinc sulfide is put on the molybdenum boat; a film is put on an unwinding device to carry out film loading; the film and the evaporation groove are sent into a vacuum bin,and evaporation coating is carried out in a vacuum coating machine; and evaporation is stopped to carry out cooling, indoor air enters the vacuum bin, and the film is taken to obtain the zinc sulfidefilm. According to the method for preparing the zinc sulfide film, the quartz tube is additionally arranged in the evaporation groove, the molybdenum boat is flatly installed above the quartz tube, and a quartz tube pad plays a role in radiating and supporting and leveling the molybdenum boat at the bottom of the molybdenum boat; and the molybdenum boat is flatly placed so that the zinc sulfide can be uniformly evaporated in the vacuum bin. According to the zinc sulfide film prepared by the method, the arrangement mode of the zinc sulfide is changed, the prepared zinc sulfide film is good inuniformity and orderly in arrangement, and the production efficiency of zinc sulfide film prepaeation is remarkably improved.

Description

technical field [0001] The application belongs to the technical field of film preparation, and in particular relates to a method for preparing a zinc sulfide film. Background technique [0002] Zinc sulfide is a semiconductor light-emitting material. Due to its stable chemical properties, rich content, non-toxic and environmental protection, zinc sulfide is currently mainly used in many fields such as optical coatings, photoconductors, and photovoltaic devices. Zinc sulfide has powdery, transparent or translucent massive polycrystalline forms. Bulk polycrystalline zinc sulfide is mainly used as infrared window material for lasers or aircraft, and is also widely used in vacuum coating. [0003] At present, zinc sulfide films are mainly prepared by thermal evaporation. Usually, the molybdenum boat filled with zinc sulfide is placed in a vacuum chamber, and under a certain degree of vacuum, it is evaporated by heating the evaporation source. When the molecular mean free path ...
