以二乙醇胺（DEA）和乙偶姻为稳定剂，采用浸渍法在四正丁醇锆（ZTNB）的异丙醇溶液中制备了氧化锆凝胶膜。在ZTNB-DEA体系的情况下，在480 °C下结晶成氧化锆，而在ZTNB-乙偶姻体系的情况下，在380 °C下结晶成氧化锆。ZTNB-DEA体系制备的凝胶膜密度高于ZTNB-乙偶姻体系。中性乙偶姻可以作为染料掺杂ZTNB凝胶膜的良好稳定剂。染料的光稳定性取决于染料与稳定剂的配合。DEA可作为抗氧化剂和电子供体分别抑制和促进染料的光分解。
Zirconia gel films were prepared by a dipping method from a 2-propanol solution of zirconium tetra-n-butoxide (ZTNB) stabilized with diethanolamine (DEA) and acetoin. In the case of the ZTNB–DEA system, crystallization to zirconia occurred at 480 °C, while in the case of the ZTNB–acetoin system it occured at 380 °C. The density of gel film prepared from the ZTNB–DEA system was higher than that from the ZTNB–acetoin system. Neutral acetoin could act as a good stabilizer for dye-doped ZTNB gel films. The photostability of dyes depended on the combination between dyes and stabilizers. DEA could act as an anti-oxidizing reagent and an electron donor to depress and accelerate the photo-decomposition of the dyes, respectively.
