Abstract
Ensuring nuclear safety has become of great significance as nuclear power is playing an increasingly important role in supplying worldwide electricity. β-ray monitoring is a crucial method, but commercial organic scintillators for β-ray detection suffer from high temperature failure and irradiation damage. Here, we report a type of β-ray scintillator with good thermotolerance and irradiation hardness based on a two-dimensional halide perovskite. Comprehensive composition engineering and doping are carried out with the rationale elaborated. Consequently, effective β-ray scintillation is obtained, the scintillator shows satisfactory thermal quenching and high decomposition temperature, no functionality decay or hysteresis is observed after an accumulated radiation dose of 10 kGy (dose rate 0.67 kGy h−1). Besides, the two-dimensional halide perovskite β-ray scintillator also overcomes the notorious intrinsic water instability, and benefits from low-cost aqueous synthesis along with superior waterproofness, thus paving the way towards practical application.

Ensuring nuclear safety has become of great significance as nuclear power is playing an increasingly important role in supplying worldwide electricity. β-ray monitoring is a crucial method, but commercial organic scintillators for β-ray detection suffer from high temperature failure and irradiation damage
Accidents in Chernobyl and Fukushima serve as poignant reminders that disasters may occur if nuclear leakage is not well prevented, developing accurate and efficient radiation monitoring technologies is an important means to ensure the safe development of nuclear energy
We found that a series of 2D halide perovskites (HPs), including DA (C = 12), tetradecylamine (TA, C = 14), cetylamine (CA, C = 16), and supernatant became transparent and the (STA) (C = 18)-based 2D HPs, can be prepared via such aqueous synthesis, corresponding X-ray diffraction (XRD) patterns can be found in Supplementary Fig. 9
Summary
Ensuring nuclear safety has become of great significance as nuclear power is playing an increasingly important role in supplying worldwide electricity. β-ray monitoring is a crucial method, but commercial organic scintillators for β-ray detection suffer from high temperature failure and irradiation damage. Ensuring nuclear safety has become of great significance as nuclear power is playing an increasingly important role in supplying worldwide electricity. We report a type of β-ray scintillator with good thermotolerance and irradiation hardness based on a two-dimensional halide perovskite. While typical clean energies such as hydropower, solar energy, and wind power still face issues of geographic restriction and long payback period, nuclear energy has rapidly developed as one of the most important electricity suppliers on earth since the 1940s4. Pointed out that the proportion of global nuclear power generation had increased from 2.00% in 1971 to 12% in 2016, making it the third largest source of electricity in the world (after hydropower and fossil fuels), and the proportion is still increasing. With the constant depletion of fossil fuels[5], nuclear energy becomes increasingly important for a long time to come. Accidents in Chernobyl and Fukushima serve as poignant reminders that disasters may occur if nuclear leakage is not well prevented, developing accurate and efficient radiation monitoring technologies is an important means to ensure the safe development of nuclear energy
