Polarization of the Luminescence of Upconversion YNaF4:Yb,Tm Single Nanoparticles

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Solvothermal technology is used to synthesize YNaF4:Yb,Tm nanoparticles. Under the impact of laser radiation at a wavelength of 980 nm, the nanoparticles exhibit strong upconversion luminescence that corresponds to the emission of Tm3+ ions as a consequence of energy being transferred from Yb3+ ions. Recordings of the emission of single nanoparticles show the spectral lines at wavelengths of 480 and 495 nm are characterized by different polarizations.
