Research on cathode material of Li-ion battery by yttrium doping LIU Liying1,QU Tao2,KANG Xiaoxue2,TIAN Yanwen2,XU Chaqing2 (1.Faculty of Materials and Energy, Guangdong University of Technology... in three cathode materials were different, so the influences on the material performance were different. The crystal structure of the three materials was not changed by Y doping. However, the crystal......
as a material system that can convert near-infrared light into visible/ultraviolet emissions by sequentially absorbing multiple photons. The studies on upconversion materials often use two rare earth(RE) ions as a sensitizer-activator pair. We investigated the influences on luminescence intensity depending on Cr-doping content(x) of hexagonal NaLu0.98-xCrxF4 Er0.02(x = 0-0.9)upconversion material......
