The performances of liquid and film-type NIR scintillation detectors based on π-conjugated polymers containing hypervalent tin(IV) compounds are evaluated. Taking advantage of the high radiation absorption of tin (Sn) and highly efficient NIR fluorescence from the π-conjugated polymers in both solution and on a film, the polymers can be used as both liquid and film-type NIR scintillators. Moreover, the radioluminescence showed good linearity across the dose rate range of 50 to 5000 mGy h−1, suggesting their practical use as NIR scintillation detectors.
