Photonic crystals provide unprecedented control over light emission, absorption and propagation, which has led to the proposal of a large variety of optoelectronic devices. Three-dimensional devices with electronic functionality have however remained elusive, as fabrication of three-dimensional, electrically active nanostructured materials remains complex. Numerous techniques have been demonstrated...
High Purcell spontaneous emission enhancement factor of 116 is achieved by integrating a self-assembled, close packed monolayer of colloidal PbS quantum dots with a L3-type silicon photonic crystal cavity.
Thanks to their low fabrication costs and the well established surface-functionalization techniques which allow their merging into a wide range of materials, wet-chemical synthesized colloidal nanocrystals are finding broad application in several fields, from pharmacology to cosmetics, food industry, textiles, optics and so on. In particular, semiconductor nanocrystals are widely exploited as quantum...
