基于N-苯基马来酰亚胺改性的量子点光刻胶制备色转换像素化薄膜
Quantum Dot Photoresists for Pixelated Color Conversion Films Based on N-Phenylmaleimide Modification
摘要
Abstract
Photolithography is a reliable method for fabricating pixelated color conversion films in Micro-LEDs,but it faces challenges related to the compatibility of quantum dots(QDs)with photoresists.This paper develops a quantum dot-compatible photoresist by modifying acrylic resin with N-phenylmaleimide(NPMI)side chains.The C==O bonds on the side chain groups form coordination bonds with quantum dots,passivating surface defects and improving the dispersion of quantum dots.This enhances the photoluminescence quantum yield(PLQY)of the photoresist solution,reaching 76.1%for red and 43.4%for green.Even after fabricating the color conversion films,the passivation effect persists,with PLQY values of 66.4%for green and 36.4%for red.The minimum pixel size achieved was a rectangular array of 10 μm×10 μm.The resin side chain modification approach in this study provides guidance for developing QD-compatible photore-sists and offers a simple and viable solution for the commercialization of full-color Micro-LED applications.关键词
