英文摘要	Mesoporous silica-gallium phosphate glasses along the composition line, xGaPO(4)(1-x)SiO2 (x = 0.5, 0.33, 0.20, 0.14, and 0.11, respectively) were prepared via the solgel route. This glass-forming range is significantly wider than that accessible by previously reported routes. The glasses exhibit a mesoporous structure with surface areas around 400 m(2)/g, after calcination at 650 degrees C. The structural evolution from liquid to gel to glass was analyzed by liquid and advanced solid-state nuclear magnetic resonance techniques. The NMR results indicate that the glasses consist of GaPO4 and SiO2 nanodomains. With increasing GaPO4 content, the sizes of the GaPO4 domains become larger. Evidence for the connection of both domains at their interfaces by P-O-Si and Ga-O-Si linkages is presented by advanced Ga-71, P-31, and Si-29 high-resolution dipolar solid-state NMR methods.
