AI Technical Summary
Existing gamma-ray detection methods rely on large instruments, the detection materials are difficult to prepare and time-consuming, liquid fluorescent probes are not portable, have high detection costs and cannot be reused, and are sensitive to environmental humidity.
A solid-state thin-film fluorescent probe made of a mixture of rhodamine B hydrazide and polyvinylidene chloride was used. The hydrogen chloride generated by gamma irradiation caused the rhodamine B hydrazide to open its ring and emit light. After detection, the ring was restored to closed state with triethylamine so that it could be reused.
It enables portable, rapid, and low-cost gamma-ray detection. The detection process is unaffected by ambient humidity, and the probe is reusable, reducing detection costs and improving efficiency.
