Abstract
Using hydrothermal synthesis NaYF4:Yb,Er upconversion nanoparticles in the form of rods were obtained. To give the nanoparticles hydrophilic properties, their surface was modified by replacing the oleate shell with L-cysteine molecules without significant changes in their photophysical properties. Visible fading of the luminescence brightness of the modified upconversion nanoparticles wasn’t observed for months.
