摘 要：A transparent glass ceramic tri-doped with Ce3+/Er3+/Yb3+ was fabricated by the high-temperature melting technique and following heat-treatment.X-ray diffraction and transmission electron microscope results demonstrated that Ca5（PO4）3F（FAP） nanocrystals,possessed with preferable emission performances for the 1.54 m transition for doping Er3+,were homogeneously precipitated among the glass matrix with a mean size of 30 nm.Addition of Ce3+ greatly enhanced 1.54 m fluorescence of Er3+ by the cross relaxation energy transfer between Er3+ and Ce3+.Meanwhile,incorporation of Ce3+ dramatically decreased the visible upconversion emission intensity of glass ceramic than that of glass,suggesting that Ce3+ might incorporate into the FAP nanocrystals.The properties of this transparent glass ceramic showed the potential application as an efficient 980 nm pumped infrared laser medium.
