摘要
根据杂化材料无机/有机组分间化学键作用的强弱,可以将杂化材料分为第Ⅰ类杂化材料(组分间通过氢键、范德华力等弱键相结合)和第Ⅱ类杂化材料(组分间以共价键相结合).其中第Ⅱ类杂化材料由于具有更高的热稳定性、发光强度以及均一性等许多优点而成为研究的热点.本文综述了近年来溶胶凝胶法制备Ⅰ、Ⅱ两种类型稀土发光杂化材料的研究进展,相比其它制备方法,溶胶凝胶法有很大的优势,所需反应温度低、制得的材料化学均匀性好以及纯度高,因而该方法有望在制备杂化材料方面得到广泛的应用.
According to the chemical bonds strength between inorganic/organic components of hybrid materials, the hybrid materials can be divided into class I （the components are linked via hydrogen bonds or Van der Waals forces） and class II （linked via covalent bonds）. The class II hybrid materials draw more attentions because of their many advantages containing higher thermal stability, luminescent intensity,uniformity and so on. Two classes＇ hybrid materials prepared by sol-gel method were reviewed. Sol-gel method has some advantages over other preparation methods in lower reaction temperature, higher uniformity and purity, and this method can be widely used in preparation of hybrid materials.
