Fabrication of glass-ceramics containing nanocrystallites of oxide semiconductor and metal nanoparticles

研究了含tio2或ZnO纳米晶的透明微晶玻璃的制备条件。研究了电介质纳米晶和金属纳米粒子的制备方法。通过仔细研究玻璃的化学成分与析出晶相之间的关系，我们证明了一种表面取向结晶（ZnO）或相选择结晶（TiO2）。另一方面，我们研究了熔融温度与玻璃网络结构之间的关系，并报道了含玻璃和微晶玻璃的铂纳米晶。这些结果表明，自组织的非均相纳米结构可以在单片玻璃陶瓷中制备。

We have investigated the preparation condition of transparent glass-ceramics containing TiO2or ZnO nanocrystalllites. The preparation of dielectric nano-crystallites and metal nano-particles has also examined. We have demonstrated a surface orientated crystallization (ZnO) or a phase selective crystallization (TiO2) by careful investigation of relationship between chemical composition of glass and the precipitated crystalline phase. On the other hand, we examined correlation between the melt-temperature and network structure ofglass, and reported Pt nano-crystallites containing glass and the glass-ceramics. These results have shown that self-organized heterogeneous nanostructure can be made in a monolithic glass-ceramics.
