ABSTRACT
The emission of rhodamine 6G and 2,5-bis(2-benzoxazolyl)hydroquinone molecules embedded in synthetic opal photonic crystals are studied in the spectral range of 520–620 nm. It is found that the intensity of spontaneous emission is suppressed in the spectral region corresponding to the photonic stop band and is amplified on its “blue” side.
