铒敏化的纳米粒子宽带近红外发光
Erbium-sensitized Broadband Near-infrared Luminescence in Nanoparticles
摘要
Abstract
Broadband near-infrared(NIR)luminescent materials have shown great promise in applications such as optical communication,biomedicine,and optoelectronic devices.However,the current research is focused on phos-phors and glasses,and it is important to develop broadband NIR luminescent nanomaterials.Here,we report an erbi-um-sensitized core-shell nanocrystal design for broadband NIR emission.Based on the structural design with suitable dopings of Tm3+and Ho3+,the broadband NIR emission covering 1.5-2.1 μm region is achieved under 980 nm and 808 nm excitations.Moreover,the emission intensity is further enhanced by introducing Yb3+and Nd3+into the sam-ple,respectively,and the energy transfer processes between them are systematically discussed.Our results present a novel approach for developing broadband NIR luminescent materials and devices.关键词
