We analyzed luminescence generated by Kr F excimer laser ablation of untreated, deorganizedand decalcified femurs of pig using time-resolved spectroscopy. The time-resolvedmeasurement was carried out for 8μs after the irradiation in the range of 350-700 nm with astreak camera system. The almost same luminescence spectra were obtained in the cases of theuntreated and deorganized bones, which differed from that of the decalcified bone. This resultindicates that these spectra are attributed to excited species of the inorganic components ofbone, which are Ca atom, Ca ion and HPO molecule. The life times of the emissions fromthese species were in the range of 0.6-1.5μs.
