Recently, Kong Xianggui, a researcher at the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences, Liu Xiaomin's research group has innovatively combined the controlled 'ionic nanopartition doping' technology and rare earth ion delayed excitation control methods with Monte Carlo computational simulation methods. For the first time, the photon energy in the multi-nano layer region is clearly described as the absorption, migration, transfer, and recombination dynamics. It vividly describes the single-time transient migration of photon energy and the “walk” random dynamic image, realizing the photon. The precise control of the dynamics process has set the direction for solving the challenging problem of low photon upconversion efficiency.
The relevant research results were published in the form of cover papers in "Applied Chemistry in Germany", Dr. Zuo Yu, and assistant researcher Tu Langping as the co-first author. This research was awarded by the National Natural Science Foundation of China, the leading talent and innovation team project in Jilin Province, outstanding Funding for youth projects, etc., and Zhang Hong, a professor at the Institute of Molecular Sciences at the University of Amsterdam in the Netherlands, supported Evert Jan Meijer in simulation calculations.
