  • Process and Composition for Making Rare Earth Doped Particles and Methods of Using Them
    Publication number: 20110101273
    Abstract: Methods for synthesizing a phosphor which is capable of upconversion fluorescence. One exemplary method includes forming a rare earth hydroxide and exposing the rare earth hydroxide to a fluorine source to produce a rare earth fluoride. Another exemplary method includes fluorinating a rare earth hydroxide without use of F2 or HF to produce a rare earth fluoride and purifying the rare earth fluoride.
