Description:

Polycrystalline Ce3+-doped fluorapatite (Ce:FAP) transparent ceramics with fine microstructures were fabricated through liquid-phase synthesis for the initial powder and spark plasma sintering (SPS) for full densification. These ceramics were confirmed to have single-phase crystal structure, and the average grain sizes were determined to be 139 and 135 nm for the 1 and 2% Ce-doping concentrations, respectively. Their emission spectra revealed that the fabricated ceramics convert UV light to visible light emission due to the 5d→4f electronic transition of Ce3+. These ceramics are expected to be useful in photonic applications.
