Si-29 and Li-7 NMR have been used to study the sol-gel process. It has been found that the doping components (such as TlNO3, LiNO2, and Cd(NO3)(2)) could promote the hydrolysis and condensation reactions and their ratio, thus they could influence the gelation time. The lithium species has been demonstrated to remain as free hydration. ions during the whole sot-gel process and not to participate in forming the inorganic network. 展开更多
