Influence of the fluorine ion content on luminescence properties of the EuII+/III+-doped silicate-substituted apatite
Source abstract
Abstract
In this study the preparation, characterization, and photoluminescence properties of the Eu 3+ -doped apatite compounds have been presented. The Eu 3+ ion doped silicate-substituted apatite, Ca 9.9Eu 0.1(PO 4) 2(SiO 4) 4(OH) 2−xF x where x = 0; 0.8; 1.2; 2.0, was obtained by a microwave-assisted hydrothermal method. A detailed investigation on the heat-treated samples was done by using X-ray diffraction (XRD), scanning electron microscopy energy-dispersive spectrometry (SEM-EDS), transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FT-IR). The luminescence behavior of Eu 3+ ion was explored based on excitation and emission spectra as well as luminescence decay profiles. The emission spectra under excitation to the charge-transfer (CT) transition shows the broad band associated with Eu 2+ ion emission. The asymmetry parameter ( R parameter) and CIE color coordinates were also discussed.
