【摘要】 用正硅酸乙酯（ＴＥＯＳ）和甲基三甲氧基硅烷（ＭＴＭＳ）为共先驱体，采用溶胶－凝胶工艺制备了掺Ｐｙｒｉｄｉｎｅ－１的有机改性硅凝胶。用差热分析（ＤＴＡ）和ＦＴＩＲ研究了凝胶的热稳定性和结构。测定了凝胶的吸收光谱和荧光光谱。更多还原

【Abstract】 TEOS and MTMS were used as Coprecur Sors. Sol gel method was adoped to prepare Pyridine 1 doped organically modified SiO 2 gel. DTA and FTIR were measured to investigate the structure and thermal stability of the gel. Absorption and fluorescence spectra of the gel were recorded.更多还原
