中文摘要：

采用水热法合成了Tb3＋和Eu3＋共掺的2ZnO.2.2B2O3.3H2O红色荧光粉。通过固定Eu3＋的掺杂浓度为3%（物质的量比：Eu∶Zn=3%）,改变Tb3＋的掺杂浓度（2%～15%）,研究Tb3＋掺杂浓度对红色荧光粉晶相结构和光学性能的影响。用X射线衍射和荧光光谱仪对样品的结构和发光性能进行表征,结果表明：随着Tb3＋掺杂浓度的升高,样品由晶态向无定形的玻璃态转变;Eu3＋的发光强度也逐渐增强;Tb3＋与Eu3＋之间存在能量传递的过程,且当采用不同的激发波长（220 nm和393 nm）激发时,其能量传递的过程也不一样。

英文摘要：

The samples of Eu3＋ and Tb3＋ co-doped 2ZnO · 2.2B2O3 · 3H2O were synthesized by hydrothermal method.In these experiments,the Tb3＋ ions doped concentration were variable from 2% to 15%,while the Eu3＋ doped concentration was fixed 3%.The crystal phase and luminescent properties of the samples were characterized by X-ray diffraction and fluorescence spectrometer.The crystal phase of the as-prepared powder was toward to glass state with the increasing of Tb3＋ ions doped content.The luminescence intensities of Eu3＋ ions increased with the increasing of Tb3＋ doped concentration were observed in emission spectra under the excitation wavelength at 220 nm and 393 nm,respectively.By analyzing the data of the emission spectra under these two excitation wavelengths,Tb3＋-Eu3＋ energy transfer was found under the former excitation wavelength,while the Eu3＋-Tb3＋-Eu3＋ energy transfer may be occurred under the later excitation wavelength.
