A facile and convenient fluorescence detection of gamma-ray radiation based on the aggregation-induced emission

Abstract

A facile and convenient fluorescence detection of gamma-ray radiation is reported. This is based on the ensemble of silole 1 and polymer 2, by taking advantages of AIE (aggregation-induced emission) behavior of silole compounds and the fact that polymers with –SO₂groups in the main chain can be degraded upon gamma-ray radiation. The fluorescence intensity of the ensemble of silole 1 and polymer 2 decreases gradually after exposure to increasing dose of gamma-ray radiation. The detection of gamma-ray radiation with silole 1 and polymer 2 can be performed at ambient conditions and gamma-ray radiation as low as 0.13 kGy dose can be successfully detected.
