建立了一般意义上的单分子 -光子泵模型 ,并用计算机模拟了在不同能量的光子激发下单个分子作为制冷泵时的量子跃迁过程 ,研究了单分子 -光子泵处于基态和激发态时的热激发过程以及在发生荧光辐射时的声子参与情况 ,得出了基态具有较强的制冷能力的结论。基态和激发态在光吸收和发射过程中热力学效应是不同的 ,因此在选择反斯托克斯荧光制冷材料时 ,发光中心的基态能级劈裂更具重要性
A general model of single-molecule-photon pump is established. The quantum transition process of a single molecule as a refrigeration pump under different excitation energy of photons is simulated, and the heat of the single-molecule photon pump in the ground state and the excited state is studied Excitation process and phonon participation in the case of fluorescence emission, the conclusion is drawn that the ground state has a strong cooling capacity. The ground state and the excited state have different thermodynamic effects during light absorption and emission. Therefore, when selecting anti-Stokes fluorescent refrigerants, the ground state splitting of the luminescent center is more important
