Description:
This paper deals with the luminescence characteristics of an analogue of the mineral component of dental enamel of the nanocrystalline B -type carbonate-substituted hydroxyapatite (CHAP) with 3D defects (i.e. nanopores of ∼2-5 nm) on the nanocrystalline surface. The laser-induced luminescence of the synthesized CHAP samples was in the range of ∼515 nm (∼2.4 eV) and is due to CO 3 groups replacing the PO 4 group. It was found that the intensity of the luminescence of the CHAP is caused by structurally incorporated CO 3 groups in the HAP structure. Furthermore, the intensity of the luminescence also decreases as the number of the above intracentre defects (CO 3 ) in the apatite structure declines. These results are potentially promising for developing the foundations for precise methods for the early detection of caries in human solid dental tissue.
