Hydroxyapatite Ca 10 (PO 4 ) 6 (HO) 2 is well-known due to its characteristics such as
biocompatibility and osteoconductivity which makes it a perfect biomaterial for
applications like landfills of bones, coverings in dental prosthesis, etc. [1] [2]
Additionally, hydroxyapatite particles present other properties such as protein
or drug carrier, gas sensing and ionizing radiation dosimeter. The synthesis of
HAp nanoparticles opens a wide range of applications due to their high surface
area and a rough surface [3]. In the present work, the hydroxyapatite was
synthesized by hydrothermal method employing calcium hydroxide and
ammonium phosphate as precursors and sodium citrate as a controller of size
and shape; the pH has remained constant (pH7). XRD, SEM, EDS, AFM and FT-IR.
techniques were employed for obtaining the structural and morphological
properties of the synthesized nano-HAp. The SEM confirms the formation of
particles with nano size and defined shape. AFM analysis reveals that, the
particle size of nano- HAp is in the range of 7-60 nm. According to the XRD
analysis, the monoclinic crystalline phase was identified. The Rietveld analysis
was agree with XRD analysis, but it was possible identified presence of minimal
quantities of the hexagonal phase. Then, the thermoluminescence (TL)
properties of nano-Hap including dose response, reusability and fading were
studied when nano-Hap are exposed to gamma radiation using a 60 Co source.
TL results of nano-Hap make it a good candidate for radiation measurements in
different application.
