Theeffect of freon heat treatment on optical properties of Er-doped silica glasses obtained by the sol-gel method was investigated. It was found that fluorine ions in the process of hydrolysis replace hydroxyl ions in the host and form the complexes with Er^{3+} ions. It leads to a significant improvement of optical properties of Er doped silica glass.

The luminescence characteristics of Eu^{3+} ions in Eu(NO_{3})_{3}·6H_{2}O salt contained in polymer films coating the silver metallic surfaces were studied. The surfaces were specially prepared to consist of silver tip arrays with the height of tips in micron and surface density in 10^{-8} cm^{-2} ranges. The evaluation of enhancement per one europium ion gave a value 3.5 10^{2} for one polymer layer coating of tip array silver surface in comparison with the case of glass substrate coating.
