MAPbBr3量子点微薄膜喷印工艺调控特性研究
Study on regulation characteristics of printing MAPbBr3 quantum dot micro-films
摘要
Abstract
Perovskite quantum dot films demonstrate significant application potential in advanced display and lighting technologies.However,the electrohydrodynamic printing process was susceptible to environ-mental interference,resulting in poor printing stability and non-uniform droplet diameters,which limited the scalable array fabrication of quantum dot micro-films.In this study,a regulation method of ambient rel-ative humidity on the diameter and ejection stability of printed MAPbBr3 quantum dot micro-films was con-structed,and the effects of ambient relative humidity and applied voltage on the printed film diameter as well as the jet rheological process were investigated.Experimental results indicated that stable printing of MAPbBr3 quantum dot micro-films could be achieved under conditions of ambient relative humidity of 50%-75%and applied voltage of 2.0 kV.As the ambient relative humidity increased from 55%to 70%,the average diameter of the printed MAPbBr3 quantum dot micro-films was reduced from 198 μm to 134 μm,with CV values below 0.1.When the ambient relative humidity was increased to 75%under an applied voltage of 2.3 kV,the average diameter of the printed MAPbBr3 quantum dot micro-films could be further reduced to 69 μm.The regulation mechanism on the printing quality of MAPbBr3 quantum dot micro-films is beneficial for enhancing the large-scale fabrication level of perovskite quantum dot film arrays.关键词
