We described an improved solgel process to prepare pyridinephenol ligand (dppyBF doped silica composie glass.

利用新型溶胶凝胶方法制备一种酚基吡啶硼配合物(dppyBF掺杂的二氧化硅复合发光玻璃。

In this dissertation, based on glass microspheres and submicron silicon dioxide, the silver-coated core-shell shielding particles were prepared by liquid phase chemical deposition and layer by layer packing technology. The influences of the preparation conditions on the structure of the synthesized core-shell particles were also systemically studied. The conclusions are enumerated as follow:(1) Monodispersed submicron silicon dioxide spheres in the size range of 250～550 nm are synthesized by Sol-Gel method using ammonia as catalyst.
