These three kinds of materials can be applied to the white light-emitting diode, quantum dots all-solid-state Li-O2/Li-CO2 batteries, and thermal therapy. The detailed information of these three kind materials incorporated in the following sections: (a) Converting materials from light to light 1. We plan to use the Hot Isostatic Press (HIP) system to synthesize narrow bandwidth nitride phosphors and normal pressure synthesized broad bandwidth infrared phosphors. Analyze their structure information and photoluminescence properties. 2. We plan to use the Hot Isostatic Press (HIP) system to synthesize narrow bandwidth nitride phosphors and broad bandwidth infrared phosphors by tuning the chemical composition and the doping elements. Explore the relationship between the structure and the synthesized solid-solution phosphors and tuning the wavelength of the photoluminescence spectrum. 3. We plan to do the package of light-emitting diodes of the as-prepared samples to analyze their practical applications. (b) Converting materials from light to electricity 1. Because of the wide range of absorption and high efficiency of quantum dots, we plan to use it in the cathode in the Li-O2/CO2 battery to reduce overpotential. 2. We plan to use Ruthenium to modify the carbon to improve the high potential and poor cycle life of quantum dots Li-O2/CO2 battery. 3. The new “quantum dot solid-state lithium-oxygen/carbon dioxide batteries” will be developed by combining quantum dot and solid-state electrolytes with Li-O2/CO2 battery. (c) Converting materials from light to heat 1. We plan to synthesize the mesoporous silica shell-coated gold nanorods (AuNR@mS) by the seed crystal growth method. AuNR@mS was assembled into nanocomposites using an electrostatic adsorption process with lanthanide-doped upconversion nanoparticles (UCNP). It can apply in cancer treatment by photodynamic therapy and photothermal therapy. 2. We plan to fabricate the nanocomposites, which will combine with nanobubbles and further modify targeting ligands for biological ultrasound imaging and cancer therapy.螢光粉量子點式全固態鋰電池光照治療phosphorquantum dot solid-state lithium-oxygen/carbon dioxide batteriesphototherapy
