Modification of the spontaneous emission of dye molecules embedded in artificial opals exhibiting stop bands in the visible range is observed. Molecules embedded in artificial opals show dips in spontaneous emission spectra and modified fluorescence decay kinetics. Results are interpreted in terms of redistribution of the photon density of states. Effects of the multiple reabsorption and reemission of fluorescence photons and interaction of dye molecules with the silica surface are discussed.

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.
