Аннотация
The effect of an incomplete three-dimensional photonic band-gap structure upon the wideband photoluminescence from bare opal and opal impregnated with ZnS has been studied by means of angular-resolved photoluminescence. It has been shown that the photoluminescence becomes anisotropic in accordance with the angular dispersion of the stop band. Suppression of the spontaneous emission in the stop-band energy region and amplification of the spontaneous emission at the edge of the stop band have both been demonstrated.
