説明
<jats:p> We report the synthesis of tetragonal-phase LiYF <jats:sub>4</jats:sub> nanoparticles doped with upconverting lanthanide ions. The nanoparticles have been characterized by XRD, TEM, and luminescence decay studies. The size of the as-synthesized LiYF <jats:sub>4</jats:sub> nanoparticles can be tuned by varying the precursor ratio of F to lanthanide ions. Passivated by oleic acid ligands, the LiYF <jats:sub>4</jats:sub> nanoparticles can be readily dispersed in a wide range of nonpolar solvents including hexane, cyclohexane, dichloromethane, and toluene. The lanthanide-doped (Yb <jats:sup>3+</jats:sup> , Er <jats:sup>3+</jats:sup> , Tm <jats:sup>3+</jats:sup> , Ho <jats:sup>3+</jats:sup> ) LiYF <jats:sub>4</jats:sub> nanoparticles show intense upconversion emissions upon near infrared excitation at 980 nm. By varying composition and concentration of the dopant ions, the color output can be precisely modulated under single wavelength excitation with a diode laser. </jats:p>
