HA molecule : Ca10(PO4)6OH2
Projection in the (001) base plan of the hydroxyapatite unit cell (hexagonal structure)
How difficult is to deposit CaPs?
- very complex molecules
a = 19.68(1) Å b = 9.50(1) Å c = 6.832(5) Å = 90.21(8)° = 92.52(9)° = 108.32(8)°
Electron microscopy of OCP revealing nano-crystalline domains embedded in an amorphous matrix
X-ray diffraction patterns are in agreement with an amorphous-poor crystalline structure. OCP presence is confirmed by the shoulder around 4.7° of 2θ, corresponding to the (100) reflection of OCP, and by the broad peak centered around 32-33° of 2θ.

We could identify a deposition regime for which the obtained structures contain crystalline CrO2
Difractograme of the film deposited from CrO3 target at room temperature, 13Pa
oxygen for a laser fluence of 2.4 J/cm2
SEM micrograph of the film deposited at 300C, 13 Pa O2
for a laser fluence of 2.4 J/cm2
Raman spectroscopy
Raman spectra of the films (Cr8O21 target, 2.4 J/cm2, 13 Pa O2) after four months of exposure to ambient air: a) gold protected film; b) unprotected film
Modified composition of the film after 4 months exposure to air
We studied the stability in time of the:
films protected with gold
versusunprotected films
No modification in the film composition within 4 months of exposure to air
