纯溴基蓝光钙钛矿的合成及其研究进展
Synthesis and research progress of pure bromine-based blue light perovskite
摘要
Abstract
This paper reviews the research progress of pure bromine group blue light perovskite materials in recent years,mainly focused on the pure bromine group blue light perovskite synthesis method and research progress,covering the thermal injection method and ligand assisted precipitation,and through ligand engineering,A position cation engineering,quasi two-dimensional structure design and B position substitution engineering strategy to optimize its performance.Ultra-small perovskite quantum dots use ligand engineering to passivate surface defects and improve quantum dot stability.The band gap can be effectively expanded by shrinking the nanocrystals lattice,leading to PL emission blue-shift,high PLQY,narrow bandwidth and sharp exciton absorption transitions.For quasi-two-dimensional blue light perovskite,organic septal cations and additives are usually choosed to regulate the number of quasi-two-dimensional perovskite layers,so that the phase is cleaner and narrower,so as to obtain better performance of blue light devices.In addition to the common passivation agents,polymers can also act as passivation agents.For example,polyvinylidene(PVDF)effectively passivate surface defects and enhances stability.These optimization strategies have made significant progress in brightness,color purity and efficiency,providing new ideas for high-performance blue light-emitting devices.关键词
