Quantum-Cutting Ytterbium Ion(Yb3+)-Doped Perovskite Nanocrystals:Synthesis and Novel Applications in Multi-Energy X-Ray Imaging
摘要
Abstract
In recent years,rare earth ion-doped perovskite materials have garnered significant attention from researchers in the field of optoelectronic functional materials due to their excellent optoelectronic properties,tunable bandgaps,and unique quantum-cutting effects.Among them,ytterbium ion(Yb3+)-doped perovskite nanomaterials,with their remarkable optical characteristics such as exceptionally large Stokes shifts,photoluminescence quantum yields exceeding 100％,and efficient near-infrared luminescence,have demonstrated immense application potential in X-ray imaging,multi-energy X-ray imaging,luminescent solar concentrators,solar cells,and near-infrared electroluminescent devices.This review focuses on the quantum-cutting properties of Yb3+-doped perovskite nanocrystals,systematically discussing the topic in two parts:comprehensively outlines the synthesis strategies,quantum-cutting luminescence mechanisms,and optoelectronic applications of Yb3+-doped CsPbCl3 nanocrystals;delves into the advancements of quantum-cutting perovskite scintillators and their latest breakthroughs in X-ray imaging,and multi-energy X-ray imaging.By analyzing the current scientific challenges and technical bottlenecks,this review also prospects future research directions and development trends,providing valuable insights for the further study and application of quantum-cutting materials.关键词
