Abstract
We have successfully synthesized colloidal lithium yttrium fluoride (YLF) nanoparticles doped with ytterbium with the goal of investigating their anti-Stokes emission. The Yb content was varied between 1% and 10%. The nanoparticles emit in near-infrared, with the emission spectrum extending from 960 nm to 1060 nm when excited with the 900 nm light. Strong anti-Stokes photoluminescence was observed when using excitation wavelengths ranging from 1000 nm to 1020 nm.
