报告摘要:

Surface modification with organic dye molecules is a useful strategy to manipulate the optical properties of lanthanide-doped inorganic nanocrystals. It enables energy transfer between dyes and the nanocrystals, which provides unprecedented possibilities to gain new optical phenomena from the organic-inorganic composite systems. The development highly efficient lanthanide-based organic-inorganic nanoconjugates may overcome the existing limitations to the lanthanide-doped nanomaterials and stimulate a number of applications in area such as light energy harvesting, light emission, biosensing, therapeutics and photocatalysis. Driven by this motivation, our group has recently devoted to the fabrication and mechanism studies of lanthanide nanocrystals with either unique surface features or novel organic-nanoparticle hybrid structures. We are trying to understand the energy transfer of organic triplets through the interface of lanthanide-doped nanocrystals for potential applications such as photovoltaics and nanomaterial therapeutics.
