采用流延法制备了含有 CMC/Tb-Eu(CTE)的羧甲基纤维素(CMC)复合荧光膜， 研究了 CTE 悬浮液的流变性能，并由傅里叶变换红外光谱(FTIＲ)、原子力显微镜 (AFM)、荧光光谱(FL)以及力学测试对复合膜的结构与性能进行了表征． 流变学结果表 明，质量分数为 2%～6%的 CTE 悬浮液保持了 CMC 溶液剪切变稀的流变特征． FTIR表 明:膜的形成过程并未改变 CTE 粒子的化学结构，即 Tb³⁺ 或 Eu³⁺ 与 CMC 发生配位和离 子交换反应;当激发波长为 374 nm 时，复合膜发射 Tb³⁺ 和 Eu³⁺ 的特征荧光光谱，其中在 543nm 处的发射峰荧光强度最大，为 Tb³⁺ 的⁵ D₄ →⁷F₅ 发射;当 CTE 添加量为 0． 2 g 时，膜 的荧光强度最强． 力学性能显示，CTE 含量增加可同时提升膜的拉伸模量和抗张强度，断裂 伸长率变化没有显著性差异，膜的最大拉伸模量为4．179GPa，最大抗张强度为78．76MPa．

The carboxymethyl cellulose (CMC) composite fluorescent films with CMC/Tb-Eu (CTE) were pre- pared by casting method，and the rheological properties of CTE suspensions were studied． The structure and pro- perties of composite films were characterized by Fourier transform infrared spectroscopy (FTIR)，atomic force microscopy (AFM)，fluorescence spectroscopy (FL) and mechanical tests． The rheological results show that the CTE suspensions with mass fraction from 2% to 6% maintain the rheological characteristics of shear thinning of CMC solution． FTIR shows that process during the film formation does not change the chemical structure of CTE particles． That is，Tb³⁺  or Eu³⁺ undergoes coordination and ion exchange reaction with CMC． When the excitation wavelength is 374nm，the composite films emit a characteristic fluorescence spectrum of Tb³⁺ and Eu³⁺ ，wherein the emission peak fluorescence intensity at 543nm is the largest，which is ⁵ D₄ →⁷F₅  emission of Tb³⁺ ． When the CTE content is 0. 2g，the fluorescence intensity of the film is the strongest． The mechanical properties show that the increase of CTE content can simultaneously increase the tensile modulus and tensile strength of the film，and there is no significant difference in the elongation at break． The maximum tensile modulus of the film is 4. 179GPa and the maximum tensile strength is 78. 76MPa．
