报告内容简介： A major direction of our program is Nanophotonics which taps on nanoscale manipulation of optical interactions, control of light propagation and energy flow on nanoscale 1-2. We have placed a special emphasis on harvesting of IR photons that provide deep penetration and thus volume photoactivation. This talk will present our work on quantum dots, plasmonics semiconductors; upconverting rare-earth ion doped optical nanotranformers and switchable nanoassemblies as well as their polymeric nanocomposites as new generation nanophotonics materials for a broad range of applications including optoelectronics, biotechnology, and environmental sensing and decontamination1-3 Hybrid nanostructures, their assemblies and their nanocomposites, with their nanophotonic control, will provide new approaches for optoelectronics. The three optoelectronics technologies, all utilizing interconversion of optical and electrical energies, to be discussed are LEDs, photorefractive media and solar cells. Our program utilizes multifunctional polymer: quantum dot nanocomposites for these applications, with a particular focus on the IR communication wavelengths. We are developing new approaches for efficient harvesting of solar photons over the entire solar spectrum. Our emphasis is to enhance ultraviolet photon utilization, as well as to harvest IR photons that are unutilized currently. A major approach by us is utilizing optical nanotransformers which shift photons from UV and IR to visible to be efficiently absorbed by the existing solar devices. We are developing new directions in biotechnology utilizing Nanophotonics, with a global vision to produce breakthrough approaches for meeting our current and future healthcare challenges such as cancer, neurological disorder, infectious diseases, age-related diseases, addiction, chronic pain, depression and obesity1-3. Our research in utilizing Nanophotonics for multimodal bioimaging (Fluorescence, CARS, SHG, Photoacoustic), sensing, and light-activated therapy will be highlighted. It will present nanotechnology-based and light-guided gene therapy, and stem cell therapy for repairing or replacing malfunctioning cells and tissues in the aging population. It will also present a thought provoking revolutionary concepts of rejuvenation therapy that may allow a human to live for 1,000 years or more, and of human-machine interfacing using magneto-optic nanocomposites to measure brain waves and quantify mental capacity. This talk will conclude with a discussion of future outlook and new opportunities in these fields. P. N. Prasad"Nanophotonics"John Wiley &Sons, (2004). P. N.
