  Rare-earth-doped optical materials are important for light sources in
optoelectronics, as well as for efficient optical amplification elements and
other elements of photonics. On the basis of the previously developed method of
anhydrous, low-temperature synthesis of Er/Yb oxides from their chlorides we
fabricated proper nanoparticles with defined parameters and used them for the
development of optically transparent, luminescent polymer nanocomposite with
low optical scattering, suitable for direct, light-induced formation of
photonic elements. Introduction of preformed gold nanoparticles in such a
nanocomposite was also performed and an enhancement of luminescence due to the
influence of plasmon effects was detected.
