Opis:: 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.

Opis:: The energy spectrum of a quantum dot made from IV-VI narrow gap semiconductors is studied. The calculations of the energy levels as functions of the dot radius are performed. When the anisotropy of the bare energy spectrum is strong, the energy levels are calculated using Fal'kovskii's adiabatic approximation for multiband systems. When the quantum dot material has an inverted band gap with respect to the host, the low-energy states within the fundamental gap are shown to arise.

Opis:: We present the first experimental observation of narrow dips in the fluorescence profiles of completely closed hyperfine transitions in Rb vapor at high atomic density, which is attributed to the depolarization of the excited state. Moreover, at low atomic density, a narrow peak on the top of the fluorescence profile is demonstrated, centered at the completely closed transition within the $D_{2}$ line of Cs. Experiments are performed in thin (700 μm) alkali cell by single light beam spectroscopy. The cell is filled with Cs containing a small portion of Rb.
