摘要：
Turn-on mode fluorescent diarylethenes such as 1,2-bis(2-alkyl-6-phenyl-1-benzothiophene-1,1-dioxide-3-yl)perfluorocyclopentene were applied to ultrahigh-sensitive fluorescence dosimeters. The dosimeters can detect absorbed dose as low as 50 mGy. The sensitivity is 10(2)-10(3) times higher than that of conventional colour dosimeters. (C) 2020 Elsevier Ltd. All rights reserved.
