Resumo

We studied the possibility of using upconversion fluoride nanoparticles NaYF4 doped with Yb3+ and Er3+ ions as ordered non-invasive hidden labels. The synthesized upconversion fluoride nanoparticles were first deposited from suspension onto the surface of the substrate with labels used as large-scale markers, and then, using a scanning probe microscope, small conglomerates of upconversion nanoparticles were transferred over macroscopically significant distances and controlled deposited onto a clean surface, thereby imprinting nanoobjects. The process of transfer and deposition was monitored using a conventional optical microscope. Luminescent signals from orderly located labels were recorded in an optical confocal microscope.
