| 报告介绍 | Abstract：
Multiphoton processes with highly efficient frequency upconversion of infrared (IR) light to shorter wavelengths open up opportunities for many technological applications. They can provide the function of on-demand and on-site optical transformers. The two types of materials being developed in our lab are nonlinear organics and rare-earth doped fluoride nanocrystals. These nanocrystal can transformer deep penetrating near IR light to a shorter wavelength (covering visible to UV) in a selected deep volume spot to activate a desired photoprocess. The physics of excitation dynamics in these nanotransformers can be controlled by using nanochemistry to produce hierarchically built core-multiple shell nanostructures and tailor their interfaces. The applications of this photon upconversion technology being pursued in our lab include IR harvesting of photons for photovoltaics, high contrast bioimaging, functional photoacoustic imaging, photodynamic therapy, light activated drug release and optogenetics.
Biosketch: PARAS N PRASAD, Ph.D. is a pioneer in Nonlinear Optics, Biophotonics, Nanotechnology, Nanophotonics and Nanomedicine. He was named among the top 50 sciences and technology leaders in the world by Scientific American in 2005, and is on the Thompson Reuters “Highly Cited Researchers” list for 2014. He published over 740 scientific and technical papers in high-impact journals; four monographs that practically defined the fields of organic nonlinear optics, Biophotonics, Nanophotonics, Nanobioengineering and Nanomedicine; eight edited books; and holds numerous patents. He received many scientific awards and honors (Morley Medal; Schoellkopf Medal; Guggenheim Fellowship, Sloan Fellowship; Western New York Health Care Industries Technology/Discovery Award; Excellence in Pursuit of Knowledge Award of the SUNY Research Foundation; the University’s First Innovation Impact award; Fellow of the APS, OSA, and SPIE). Prasad received in 2015 the inaugural Innovation Award for his most successful invention of Nanomedicine that formed the basis for the publically trading company Nanobiotix based in Paris, valued for over 300 million dollars. |
