绿光InP基量子点发光性能提升策略:表面钝化与配体工程OA

Colloidal quantum dots(QDs)are recognized as the key luminescent materials for next-generation display and lighting technologies,owing to their unique size-dependent luminescent properties,high color purity,and high photoluminescent quantum yield(PLQY).Among various QDs,indium phosphide(InP)quantum dots show particular promise for future displays and lighting applications due to their environmentally benign characteristics,broad spectral tunability,and cost-effective solution processability.This article provides a systematic review of recent advances in green-emitting InP QDs,highlighting three critical breakthroughs.First,in the aspect of chemical synthesis,precise regulation of reaction kinetics has enabled the fabrication of green-emitting InP core particles with uniform size and high crystallinity.Second,in terms of surface passivation,both ionic and shell passivation have been implemented to effectively suppress surface defect states in the core,leading to a significant improvement in the PLQY.Third,in terms of ligand engineering,the modification of surface ligands has yielded stable InP QDs with suitably aligned energy levels.Furthermore,the paper presents an outlook on their future development directions.
