Abstract
Fluoridated hydroxyapatite (Ca10(PO4)6(OH)2-2xF2x; FHAp) is expected to be much more effective than
hydroxyapatite (HAp) in medical and dental applications due to its good acid-resistance. In this paper, we
report the results of fabrication of FHAp films and in vitro evaluation of its biocompatibility. FHAp films
were deposited on Ti substrates by PLD using an ArF excimer laser. XRD results showed that the length
of the a-axis of FHAp film decreased compared to the standard length of HAp. In the FT-IR analysis, it was
confirmed that part of OH－ was replaced by F－. From the FT-IR analysis, the FHAp film yielded a fluorine
signal. In the in-vitro cell test, it was proven that FHAp film showed excellent cell proliferation of the degree
equal to HAp film. These results indicate that we succeeded in the fabrication of FHAp film that is very useful
as the implant coating material in the next generation.
