| 摘 要： | 通过以TeO2,GeO2,ZnF2,SiO2,PbF2等为主体的氟氧化物玻璃陶瓷基质材料的研究提出了提高上转换效率的某些条件.选择低声子能量的基质,且基质的M系数接近稀土离子的M系数的氟氧化物基质材料是高效上转材料的基础,选择激发光光子能量与稀土离子、敏化稀土离子能级匹配是高效上转换材料的必要条件.为设计研究稀土掺杂能量上转换材料提供了有理论和应用价值的结果.

| Abstract: | Some conditions are put forward about improving the up-conversion efficiency through study of oxy-fluoride glasses based on TeO2,GeO2,ZnF2,SiO2 and PbF2. Hosts with low phonon energy benefit the energy up-conversion.It is also found that when the value of the quasi-field parameter of the oxy-fluoride host is adjusted near to that of the M parameter of the doped rare-earth, the materials show high up-conversion efficiency.Selecting suitable excitation photon energy to match the level of rare-earth ions and/or sensibilizer ions is a necessary condition for high up-conversion efficiency.The results provide some practical guidance to prepare rare-earth doped energy up-conversion materials. |
