We report on cost-effective recycling of crab shell biowaste and synthesis of luminescent powders. XRD, thermogravimetric and, FTIR analysis revealed that calcination temperature must be beyond ∼800 °C to recycle biowastes crab (Ucides cordatus) shell into crystalline powder composed of CaO, and a small amount of CaCO₃, NaCa(PO₄), MgO, and Ca₁₀(PO₄)₆(OH)₂. SEM analysis revealed that calcination of crab shell biowaste at 800 °C/2 h produced the homogeneous cauliflower- and ixora flower-like shaped intrinsic luminescent powders. XEOL and thermoluminescence analyses suggest that F⁺-centers of the CaO structure are responsible for the efficient intrinsic scintillation of the crab shell powder. Therefore, our study shows a biomaterial promise derived from seafood wastes as natural dosimeter materials for industrial applications.

我们报告了蟹壳生物废料的成本效益回收和发光粉的合成。XRD，热重分析和FTIR分析表明，煅烧温度必须超过〜800°C，才能将生物废料蟹壳（Ucides cordatus）回收成由CaO和少量CaCO ₃，NaCa（PO ₄），MgO，和Ca 3（PO 4）3（OH）2。扫描电镜分析表明，在800°C / 2 h下对蟹壳生物废料进行煅烧可产生均匀的菜花状和草状的固有发光粉末。XEOL和热致发光分析表明，F ⁺CaO结构的中心负责蟹壳粉的有效内在闪烁。因此，我们的研究表明，源自海鲜废物的生物材料有望作为工业应用中的天然剂量计材料。
