Resumen
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 Ca??????(PO???)???(OH)???. 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.
