Ytterbium-doped Sr5(PO4)3F transparent ceramics have been developed through spark plasma sintering (SPS) with a low sintering temperature and short dwelling time. The XRD patterns show a polycrystalline hexagonal phase, and the TEM microstructure characterization indicates that the ceramics have a narrow grain size distribution which ranges from 40 to 200 nm, with an average grain size around 150 nm. The transmittance of a 2 mm thick ceramic sample is measured to be 74% at 1000 nm by a UV–Vis… CONTINUE READING
