采用共沉淀法合成了 5 at.% Eu 掺杂 CaF2 纳米粉体。 X射线衍射(XRD)表明样品对应于立方CaF2相，扫描电子显微镜(SEM)表明纳米粉末的形貌近似球形。采用真空环境下不同P-T条件下热压(HP)法制备Eu:CaF2透明陶瓷。还研究了断裂面、相对密度、平均晶粒尺寸和收缩位移，分析了烧结条件对Eu:CaF2陶瓷的影响。与其他样品相比，合适的烧结温度和压力为600℃/30MPa。陶瓷在760 nm和2400 nm波长下的透过率分别高达79.7%和88.85%。此外，还讨论了 Eu: CaF2 透明陶瓷在 393.5 nm 激发下的发射光谱。
Nanopowders of the 5 at.% Eu doped CaF2have been synthesized by co-precipitated method. X-ray diffraction (XRD) indicated that the samples corresponds to the cubic CaF2phase and scanning electron microscopy (SEM) showed that the morphology of nanopowders were approximately spherical. The Eu: CaF2transparent ceramics were fabricated by hot-pressing (HP) method at different P-T conditions in a vacuum environment. The fracture surface, the relative density, average grain size and shrinkage displacements were also studied to analysis the influence of sintering conditions on Eu: CaF2ceramic. In comparison with other samples, the proper sintering temperature and pressure was 600 °C/30 MPa. The transmittance of ceramic was up to 79.7% and 88.85% at the wavelength of 760 nm and 2400 nm. Furthermore, the emission spectra of Eu: CaF2transparent ceramics under 393.5 nm excitation was also discussed.
