a Normalized radioluminescence spectra and the related photographs of PNBr, PDBr, and PIBr copolymer films under the irradiation of a dose rate of 278 μGy s−1, respectively. b CIE chromaticity coordinate diagram of the radioluminescence color of the copolymers. c Lifetime decay curves of emission bands at 546, 555, and 575 nm for PNBr, PDBr, and PIBr copolymer films, respectively, under UV light excitation. d Radioluminescence (RL) intensity variation of PNBr, PDBr, and PIBr copolymer films with different molar feed ratios of two monomers by X-ray irradiation at a dose rate of 278 μGy s−1. Note that the examination was quantitative for each group.
