我们报告了嵌入在三维固态光子晶体中的染料分子的自发发射的修改，该晶体在可见光范围内表现出阻带。与参考聚合物基质中的染料荧光相比，嵌入聚合物填充的人造蛋白石中的分子显示出荧光光谱的下降和包含加速和抑制成分的非指数自发衰变动力学。结果根据光子晶体中光子态密度的重新分布来解释。 [S0031-9007(98)06494-1] PACS 编号：42.50。 -p
We report on modification of the spontaneous emission of dye molecules embedded in a threedimensional solid-state photonic crystal exhibiting a stop band in the visible range. Molecules embedded in artificial opal filled with a polymer show a dip in the fluorescence spectrum and nonexponential spontaneous decay kinetics containing both accelerated and inhibited components compared to the dye fluorescence in a reference polymer matrix. Results are interpreted in terms of redistribution of the photon density of states in the photonic crystal. [S0031-9007(98)06494-1] PACS numbers: 42.50. ‐ p
