Description

technical field [0001] The invention relates to the technical field of nano-film materials, in particular to a method for preparing a zinc oxide nano-film under low temperature conditions and an application thereof. Background technique [0002] Zinc oxide is a typical direct bandgap semiconductor with good piezoelectric properties, good thermal stability, abundant synthetic raw materials and low preparation cost. Compared with ordinary zinc oxide particles, zinc oxide nanoparticles have higher surface energy, better photoelectric properties, and wider application prospects. They are widely used in liquid crystal displays, thin film transistors, and light-emitting diodes in the semiconductor field. Since many organic materials are not resistant to high temperatures, it is more important to spin-coat ZnO nanoparticle films at low temperatures. [0003] There are various methods for synthesizing zinc oxide nanoparticles, such as solid-phase method, chemical precipitation meth...
