Abstract

Three-dimensional (3D) inverse opal photonic crystals present the advantage of a large surface to volume ratio, which permits to allocate a high number of chromophores that can be used (i.e) for the development of highly efficient optical devices and sensors based on fluorescence detection. In this work, Er 3+ -activated inverse opals (ErIO) were synthesized using a polystyrene (PS) template by the sol-gel method. It has been observed that the ErIO spontaneous decay rates (SDRs) are modified with respect to the bulk counterparts (ErR) due to the spatial modulation of the effective refractive index n eff at the nanoscale.
