发现了一种简便的一步法制备具有新颖光学性能的氧化锌-染料杂化空心球的方法。在十六烷基三甲基溴化铵(CTAB)中加入伊文思蓝(EB)染料，通过离子自组装过程形成CTAB-EB胶束，在温和的回流条件下，加入锌盐和氨水，生成的材料可作为氧化锌结晶的软模板。并对这种空心球的形成机理进行了探讨。这些新型的氧化锌-染料混合空心球显示出与纯氧化锌和染料组分不同的光学性质。该方法是制备具有独特电学和光学性质的新型半导体染料杂化材料的一种新的有效方法，有望获得更多具有新颖结构和特殊功能的无机-有机材料。
A facile one-step process for the fabrication of hybrid Zno-dye hollow sphere with novel optical properties has been discovered. Addition of Evans blue (EB) dye to cetyltrimethrylammonium bromide (CTAB) results in the formation of CTAB-EB micelles through an ionic self-assembly process, and the resulting material acts as a soft template for the crystallization of Zno upon addition of a zinc salt and ammonia under mild refluxing conditions. The formation mechanism of such hollow spheres has been investigated. These new hybrid Zno-dye hollow spheres display distinct optical properties that differ from properties observed for the pure Zno and dye components. This approach is a new and effective method for fabricating novel semi-conducting-dye hybrids with unique electronic and optical properties and is expected to provide access to additional inorganic-organic materials with novel structures and unusual functionalities.
