抄録

Er³⁺–Yb³⁺ co-doped CaO–WO₃–SiO₂–B₂O₃–NaF glass ceramics containing CaWO₄ crystals were prepared by the melt-quench and crystallization method. The luminescence effect of the glass ceramic sample which was maintained for 70 min at 750°C exhibited the highest emission peak intensity in this work. As the crystallization time increased, the amount and the size of crystals increased and the crystal shape transformed from sphere to irregular polyhedron. Green and red up-conversion light appeared in the glass ceramics excited by 980 nm. Two emission peaks of green band at 525 and 545 nm correspond to ²H_11/2→⁴I_15/2 and ⁴S_3/2→⁴I_15/2 energy transitions of Er³⁺ ions and red band emission peak at 655 nm is correspond to ⁴F_9/2→⁴I_15/2 energy transitions of Er³⁺ ions. The up-conversion mechanism of Er³⁺–Yb³⁺ doped glass ceramics were investigated and the effect of excitation power on green and red light was analyzed. The up-conversion fluorescence intensity of the glass ceramics is the highest when the content of Er₂O₃ is 0.5 wt % and the content of Yb₂O₃ is 4.5 wt %.
