Abstract

Photonic crystals based on artificial colloidal silica crystals (opals) exhibit pronounced stop bands for electromagnetic wave propagation and the corresponding modification of the photon density of states in the visible range. Doping of these structures with dye molecules and semiconductor nanoparticles (quantum dots) provides a possibility to examine the predictions of the inhibited spontaneous emission in photonic band-gap materials. First experiments are reviewed in which pronounced modification of spontaneous emission spectra and noticeable changes in decay kinetics were observed.
