Study of optical and luminescent properties of nanocrystals NaYF4:Tm3+, Yb3+ in the UV range in the application of integrated optics

Studied the photoluminescence properties of synthesized nanocrystals doped with rare-earth ions NaYF4:Tm 3+ , Yb 3+ , 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: Yb 3+ , Tm 3+ as the prospect of a compact source of radiation in the visible and UV range.
