| 摘 要： | 用蒸发溶液法从磷酸溶液中首次生长出一系列Ce_xTb_(1-x)P_5O_(14):Mn晶体。它们属于单斜晶系,空间群P2_1/c。计算了晶格常数,用EPR结果确定在晶体中锰离子呈二价。测定了Ce_xTb_(1-x)P_5O_(14):Mn晶体的光谱,说明在晶体中存在着Ce~(3+)到Tb~(3+)和Mn~(2+)的能量转移。Mn~(2+)和Tb~(3+)的发射峰重叠,并使Tb~(3+)的发射峰增强。

| Abstract: | A series of Ce_xTb_(1-x)P_5O_(14): Mn erystals have been grown from phosphoric acid solution by an evaporation mcthod. The structure of crystal was measured. It was found that Ce_xTb_(1-x)P_5O_(14): Mn belongs to monoclinic system, space group P2_1/c. The lattice parameters have been calculated, EPR data showed that the manganese. ion has a valency of two in Ce_xTb_(1-x)P_5O_(14): Mn. The spectra showed an energy transfer from Ce~(3+) to Mn~(2+), and Tb~(3+) in Ce_xTb_(1-x)P_5O_(14): Mn. The emission peaks of Mn~(2+) and Tb~(3+) are overlaped and the peak of Tb~(3+) is increaced. |
