Abstract
In this paper, anisotropic transparent ceramics of 2 at.% Nd3+ doped Sr5(PO4)3F (Nd:S-FAP) was fabricated using the synthesized Nd:Sr5(PO4)3F particles as reaction materials by a simple sintering route of hot-pressing method for the first time. XRD results proved that the nanoparticles sizes of the synthesized powder were 23 nm. Dense microstructure of transparent ceramic and the maximum relative density was obtained by sintering temperature of 1200 °C for 1 h. The transmittance of the ceramic at the wavelength of 400 nm and 1200 nm were 45% and 50%, respectively. SEM images proved that the grain size of the fabricated ceramics was 1 μm. Spectra properties of Nd:Sr5(PO4)3F transparent ceramics were also investigated.
