Abstract
The present invention relates to a metal-organic hybrid lattice material and the application in the detection of radiation sources. In the invention, a water-soluble thorium salt and 2,2':6′,2′-terpyridine-4′-carboxylic acid are subjected to a solvothermal reaction in water and an organic mixed solvent to obtain a metal-organic hybrid lattice material. The crystalline material produces radiation-induced discoloration and photoluminescence change under ultraviolet light, X-ray, γ-ray, β-ray, and so on. The material is useful for qualitative and quantitative detection and calibration after high-dose irradiation. Compared with the traditional radiation-induced color change indicator labels, the material achieves the visual qualitative and quantitative detection and has strong radiation stability, high reuse rate, wide detection range, and good linear relationship, to solve the problem of traditional materials relying on professional optical equipment to quantify the radiation dose.
