采用常规高温熔融法合成了Yb3+/Er3+/Tm3+共掺杂磷酸盐玻璃。将前驱体玻璃退火后，得到磷酸盐玻璃陶瓷(GC)。通过X射线衍射(XRD)谱的测量，证明磷酸盐GC中存在LiYbP4O12和Li6P6O18纳米晶体。 GC 的上转换（UC）发射强度明显强于玻璃。原因是玻璃陶瓷中稀土离子之间的距离较短，增加了从敏化离子（Yb3+）到发光离子（Er3+和Tm3+）的能量跃迁。通过研究UC发射对泵浦功率的依赖性，玻璃中Er3+离子的523和546nm绿光发射是双光子过程。但在玻璃陶瓷中，它们是二/三光子过程。该现象意味着三光子过程参与了两次绿色排放的总体。利用Dexter理论，我们讨论了Er3+和Tm3+的能量跃迁。结果表明，GC中Tm3+向Er3+的能量转变非常强烈，这改变了Er3+的UC排放的布居机制。
By conventional high-temperature melting method, Yb3+/Er3+/Tm3+co-doped phosphate glass was synthesized. After annealing the precursor glass, the phosphate glass ceramic (GC) was obtained. By measuring the X-ray diffraction (XRD) spectrum, it is proved that the LiYbP4O12and Li6P6O18nano-crystals have existed in the phosphate GC. The up-conversion (UC) emission intensity of the GC is obvious stronger compared to that of the glass. The reason is that the shorter distance between rare earth ions in the glass ceramic increases the energy transitions from the sensitized ions (Yb3+) to the luminous ions (Er3+and Tm3+). By studying the dependence of UC emissions on the pump power, the 523 and 546nm green emissions of Er3+ions in the glass are two-photon processes. But in the glass ceramic, they are two/three-photon processes. The phenomenon implies that a three-photon process has participated in the population of the two green emissions. Using Dexter theory, we discuss the energy transitions of Er3+and Tm3+. The results indicate the energy transition of Tm3+to Er3+is very strong in the GC, which changes the population mechanism of UC emissions of Er3+.
