We have measured and fitted the kinetics of luminescence of Ag nanoclusters homogeneously dispersed within the bulk of an oxyfluoride glass, with various sample temperatures. The balance equations for the populations of the excited singlet and triplet states of the Ag nanoclusters are proposed and used in this fitting while taking into account inter-system crossing between the singlet and triplet states and their wavelength dependent spontaneous decay to the ground singlet state. The involved energy barriers and rate constants and spontaneous emission cross-sections for the excited singlet and triplet states are evaluated.
我们已经测量并拟合了在各种样品温度下均匀分散在氧氟化物玻璃中的银纳米团簇的发光动力学。在拟合过程中，我们提出并使用了银纳米团簇的激发单重态和三重态的布居平衡方程，同时考虑了单重态和三重态之间的系间窜越以及它们波长相关的自发衰减到基态单重态。评估了涉及的激发单重态和三重态的能量势垒、速率常数和自发发射截面。
