主 题：lanthanide excitation luminescence
摘 要：The continuously growing importance of information storage,transmission,and authentication impose many new demands and challenges for modern nano-photonic materials and information storage technologies,both in security and storage ***,luminescent lanthanide-doped nanomaterials have drawn much attention in this field because of their photostability,multimodal/multicolor/narrowband emissions,and long luminescence ***,we report a multimodal nanocomposite composed of lanthanide-doped upconverting nanoparticle and EuSe semiconductor,which was constructed by utilizing a cation exchange *** nanocomposite can emit blue and white light under 365 and 394 nm excitation,***,the nanocomposites show different colors under 980 nm laser excitation when the content of Tb3+ions is changed in the upconversion ***,the time-gating technology is used to filter the upconversion emission of a long lifetime from Tb3+or Eu3+,and the possibilities for modulating the emission color of the nanocomposites are further *** on the advantage of multiple tunable luminescence,the nanocomposites are designed as optical modules to load optical *** work enables multi-dimensional storage of information and provides new insights into the design and fabrication of next-generation storage materials.
