Title: Engineering spontaneous emission in a quantum-dot-doped polymer nanocomposite with three-dimensional photonic crystals
Author(s): Ventura, Michael J.; Gu, Min
Abstract: A method is proposed for inhibition of spontaneous emission within a stop-gap of a 3D PC fabricated within a PbSe-QD-doped polymer nanocomposite. The study observed that the new thick PC-based nanocomposite materials can control QD emission and can be used for developing active photonic devices. The study synthesized PbSe QDs by a wet-chemical method and isolated the nanocrystals from the reaction solution. A Nicolet Nexus Fouriers Transform Infrared Spectrometer (FTIR) and continuum infrared microscope were used to measure the infrared transmission. It was observed that the direct laser method can produce high quality polymer-based 3D PCs in the NIR range. The flexibility of the polymer matrix was found suitable for doping lead-based QDs into polymer to form a nanocomposite materials.
