Abstract
A series of Zn-Doped Magnesium Hydroxyfluoride, Mg1-xZnxFOH) samples with 0 to 0.15 of x were prepared using a sol–gel synthesis and dried with vacuum technique. XRD characterization of the samples indicated the amorphous phase of Mg1-xZnxFOH similarity with MgF2. The Zn doped in magnesium hydroxyfluoride did not affected on the basic structure of magnesium hydroxyfluoride. The FTIR spectra showed the samples had a broad band at 3000-3700 cm-1 and 1620 cm-1 was indicated of adsorbed H2O molecules and a bridging hydroxyl groups, respectively. The intensity of the 460, and 550 cm-1 bands correlates to Mg-F and Mg-O vibrations. The Zn-O stretching vibration of Zn-doped magnesium hydroxyfluoride appeared at 1634 and 621 cm-1.
