Study of optical and luminescent properties of nanocrystals NaYF

Studied the photoluminescence properties of synthesized nanocrystals doped with rare-earth ions NaYF4:Tm3+, Yb3+, measured luminescence spectra and absorption in the visible and near infrared regions of 300-1000 nm. Were measured the energy of phonons these nanocrystals, the average phonon energy was 332cm−1. Made optical waveguide impregnated with nanoparticles NaYF4: Yb3+, Tm3+ as the prospect of a compact source of radiation in the visible and UV range
