Synthesized Materials

Experimental results of polymer-salt synthesis of Yb:YAG nanopowders and analysis of their structure and luminescent properties are presented. Infrared absorption spectra of synthesized materials are presented. The results of XRD analysis show that Yb:YAG nanocrystals with sizes of 18-35 nm form at a temperature of 900-1100 °С. The study on photoluminescence spectra and decay curves shows that properties of synthesized powders are close to properties of macroscopic materials produced by traditional high-temperature methods.

Infrared Absorption Spectra

The high-temperature (T = 1880◦C) Be-ions diffusion and electron irradiation influence on the AlN monocrystals optical properties were investigated. We demonstrated that Be diffusion into AlN leads to spectral properties change of the Raman scattering and infrared absorption. The analysis of the Raman and infrared absorption spectra of the AlN crystals, containing Be impurity, proves that Be impurity is a getter for intrinsic impurities, which are responsible for AlN crystals yellow color manifestation and spectral lines broadening
