The sensitization of scintillation was investigated in crosslinked polymeric composite materials loaded with luminescent gold clusters aggregates acting as sensitizers, and with organic dye rhodamine 6G as the emitting species. The evolution in time of the excited states population in the systems is described by a set of coupled rate equations, in which steady state solution allowed obtainment of an expression of the sensitization efficacy as a function of the characteristic parameters of the employed luminescent systems. The results obtained indicate that the realization of sensitizer/emitter scintillating complexes is the strategy that must be pursued to maximize the sensitization effect in composite materials.

在负载有作为敏化剂的发光金簇聚集体以及作为发光物质的有机染料罗丹明6G的交联聚合物复合材料中，研究了闪烁的敏化作用。系统中激发态粒子数随时间的演化由一组耦合速率方程描述，其中稳态解允许获得作为所用发光系统特征参数函数的敏化效率表达式。所得结果表明，实现敏化剂/发光体闪烁复合物是在复合材料中最大化敏化效果必须采用的策略。
