The main results are as follows: 1 Taking advantage of the porosity and being carrier of anodic alumina, we reported the luminescence of Eu , dye Ru L〓X〓 Ru (Ⅱ(4, 4'-dicarboxyl-2, 2'-bipyridyl)〓〓, and silica gel film anchored porous anodic alumina prepared by self-assembling and deposition.

主要内容如下： 1 利用多孔氧化铝非常高的孔隙率以及它作为载体的优点，采用自组装及沉积的方法将稀土Eu离子、凝胶和有机染料镶嵌于其中，研究了多孔氧化铝复合材料的光致发光。

It is found from experiment that when pumped by skew light along the fibre's axis, both transverse electric wave and transverse magnetic wave exist in WGM lasing emission simultaneitly. With the increase of refractive index of cladding dye solution, the wavelength spacing between TE and TM waves of which the radial mode number and angular mode number are the same value decreases, and the central lasing wavelength of WGM bluely shifts to short wavelength direction.

实验发现，在抽运光以偏斜光线方式沿光纤的近轴向抽运时，回音壁模式的光纤激光辐射中，既存在光电矢量和光纤径向垂直的横电波，也存在光电矢量和光纤径向平行的横磁波；随增益包层染料溶液折射率的增加，径向模式数和角模式数相同的TE波和TM波之间的波长差单调减小，回音壁模式激光辐射的中心波长向短波方向移动，辐射的波长范围变窄。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.

本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附，研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂，其变色范围在pH 3.8到pH 5.4；而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点，故期望利用此复合材料，经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。
