光交联技术在钙钛矿量子点显示中的应用
Application of photocrosslinking technology in perovskite quantum dot displays
摘要
Abstract
Metal halide perovskite quantum dots(QDs)exhibit outstanding optoelectronic properties,including high photoluminescence quantum yields(PLQYs),high color purity,widely tunable bandgap,and solution-processability.They hold significant application potential in next-generation high-definition and flexible displays.After nearly a decade of rapid development,the device performance of perovskite QD light-emitting diodes(QLEDs)has significantly improved,with external quantum efficiencies(EQEs)exceeding 20%for red,green,and blue devices.Currently,the main challenges for perovskite QDs in display applications are poor material stability and the fabrication of high-resolution pixels.Photocrosslinking technology—which uses specific wavelength light sources(primarily UV)to trigger crosslinking reactions in molecules containing photosensitive groups,forming three-dimensional network structures to regulate material properties—holds promise for addressing perovskite QD stability issues while enabling high-resolution patterning of QDs.This paper systematically reviews recent research advances in photocrosslinking technology within perovskite systems,focusing on design strategies for enhancing the environmental stability of perovskite materials,achieving sub-micron pixel patterning,and optimizing the performance of patterned perovskite QLEDs.关键词
