Abstract

The invention discloses a preparation method of a high-transparency photoluminescence zinc oxide and polyethylene composite coating, and belongs to the technical field of functional thin film materials. The preparation method comprises the following steps: after mechanical stirring and mixing anhydrous zinc acetate and polyethylene at a certain mass ratio, manufacturing an evaporation target material through mold pressing; then, putting the manufactured evaporation target material and a polished monocrystalline silicon and quartz glass substrate which is cleaned in advance into a vacuum room;after vacuum pumping, preparing a zinc acetate and polyethylene composite coating by adopting a pulsed laser auxiliary low-energy electron beam evaporation device; and subjecting the prepared sample to annealing treatment in a muffle furnace, so that the zinc oxide and polyethylene composite coating can be obtained. The zinc oxide and polyethylene composite coating prepared according to the preparation method has relatively strong ultraviolet light emission and weak blue light emission characteristics; and as an organic and inorganic composite coating, the zinc oxide and polyethylene compositecoating can be applied to high-performance ultraviolet detectors and photoelectric devices.

Description

technical field [0001] The invention relates to a preparation method of a highly transparent photoluminescent zinc oxide-polyethylene composite coating, which belongs to the technical field of preparation of functional thin film materials. Background technique [0002] Driven by industrial development, inorganic-organic composite materials have become an effective method for materials to obtain new comprehensive properties and special applications due to their excellent synergistic effects. As a widely studied inorganic semiconductor material, ZnO is widely used in polymers and used as functional components in various devices, such as flexible electroluminescent displays, photosensors, and antireflection coatings. In recent years, various methods for preparing zinc oxide and polymer composite coatings have been developed, such as laser ablation, ion beam method, vacuum evaporation method (thermal evaporation, electron beam), sputtering method, microemulsion polymerization me...
