dc.description.abstract | As a follow-up to the previous research, this investigation is a three-year long-term fundamental- and application-oriented research, which is attempted to develop novel highlycovalent non-oxide phosphors for solid-state lighting and nanophosphors for near-infrared (NIR) fluorescence bioimaging (FBI) and solar cells with enhanced conversion efficiency. We attempt to investigate the followings: (a) The preparation of novel highly-covalent non-oxide phosphors and investigation of their luminescence properties and applications in LED lighting. The phosphor systems that facilitate energy transfer of Ce3+→Eu2+, Ce3+→Mn2+ or Yb2+→Mn2+ in selected hosts will also be included to investigate the potential single-phased color-tunable phosphors and study the energy transfer mechanism. (b) The preparation and characterizations of NIR-NIR nanophosphors (size of 10-200 nm) with biological-window characteristics and compositions of Yb3+/Er3+, Yb3+/Tm3+, Yb3+/Ho3+, Yb3+/Pr3+-codoped YF3, YVO4, NaYF4 or ROCl (R: rare earths). With thorough characterizations on these materials, their potential applications in NIR-FBI will be evaluated. (c) The enhancement of conversion efficiency of nanophosphor-coated Si-based solar cells will be studied by utilizing spectral conversion technique and by integrating down- (or up-) shifting low-scattering nanophosphors into nanostructure of the solar cell surface. We anticipate to establish the synthetic methodology, secure processing parameters, and assure the reproducibility and reliability of the preparation of LED phosphors and the surfacefunctionalized NIR down- and up-shifting nanophosphors. The phase identification and characterizations and analysis of luminescence, microstructure, and spectroscopic properties will be simultaneously accomplished. In the second year, we will attempt to optimize the performance of synthesized LED phosphors. The fabrication of the NIR fluorescence probe and screening of biotargets for NIR-FBI studies will be evaluated and carried out. The effect of various nanophosphor coatings on the efficiency enhancement of solar cells will be also evaluated. In the third year, the NIR-NIR nano-materials synthesized and characterized and the NIR-FBI technique will be utilized to probe the image of various bio-targets, both in vivo and in vitro. The well-characterized highly-covalent non-oxide phosphors will be used to fabricate white-light LEDs and investigate the color rendering and chromaticity properties. | en_US |
