报告摘要：

Lanthanide-doped photon upconversion nanoparticles (UCNPs) are capable of converting low-intensity near-infrared light to UV and visible emission through the synergistic effects of light excitation and mutual interactions between doped ions. UCNPs have gained increasing attention for their wide applications in bioimaging, displays and photovoltaics. However, there are still some ongoing challenges for further developments. In this talk, some strategies of optically controlling the optical properties of UCNPs for extended applications will be introduced. The performance of imaging employing UCNPs, e.g., imaging depth, imaging speed, quantum yield and microscopic spatial resolution have be greatly improved for applications, such as, tissue imaging and subcellular nanoscopic imaging.
