Laser Transfer of Upconversion Nanoparticles

JETP Letters
A method of the transfer of NaYF4:Yb3+Tm3+/NaYF4 upconversion core/shell nanoparticles with an average size of 30 nm via laser-induced forward transfer is proposed. The method provides a high spatial resolution by creating a “sandwich” structure on the donor substrate: for reliable fixation, nanoparticles are located between gold layers 50 and 20 nm ...
