LANTHANIDE-DOPED FLUORIDE NANOCOMPOSITES, PRODUCTION METHOD AND APPLICATIONS

摘要

The present invention provides a lanthanide-doped fluoride nanocomposite, which comprises: a core layer, is consisting of a first compound, wherein the first compound has a sodium fluoride compound with a base material, a first lanthanide metal and a second lanthanide metal; a middle layer covering the core layer, is consisting of a second compound, wherein the second compound has a sodium fluoride compound with the base material and the first lanthanide metal; and an outer shell layer covering the middle layer, is consisting of a third compound, wherein the third compound has a sodium fluoride compound with the base material and the first lanthanide metal or a third lanthanide metal.
