Abstract

The evolution of angular-dependent photoluminescence from thin-film colloidal photonic crystals assembled from silica spheres encapsulating Rhodamine 6G dye has been investigated as a function of the time of their exposure to the incident laser irradiation. Resulting diagrams showing this angular dependence in emission reveal 3 types of behaviour which can be explained in terms of the spatial configuration of the light sourced inside the colloidal crystal due to inhomogeneous bleaching of dye emission, the ballistic propagation of photons in well-ordered crystals, and self-absorption of the emission by non-excited dye molecules.
