The Sensitization of Scintillation in Polymeric Composites Based on Fluorescent Nanocomplexes

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.

Automated summary

The sensitization of scintillation in crosslinked polymeric composite materials loaded with luminescent gold clusters aggregates and organic dye rhodamine 6G as sensitizers and emitters, respectively, was studied through a set of coupled rate equations. The results suggest that the strategy to maximize the sensitization effect in composite materials should focus on the realization of sensitizer/emitter scintillating complexes.
