平板显示器（FPD）的市场和对高效彩色发光薄膜的需求一直在快速增长。在这项工作中，薄膜获得从Pechini的溶液通过浸涂。对绿色薄膜在873 K下进行热处理，得到1at%的ZnO：Eu薄膜。使用经水热处理的Schott®玻璃板作为基材。通过光学显微镜观察，膜具有马赛克形状的特征。该特征是基板热处理的结果。薄膜沉积降低了可见光范围内的基板透射率。当激发7 F0 → 5L 6（392 nm）Eu ~（3+）跃迁时，可以探测到5D 0 → 7 FJ（J=1，2，3，4）跃迁的发射。用ZnO激发波长观察到5D 0 → 7 F2跃迁，表明能量从ZnO转移到Eu ~（3+）离子。
The flat-panel-display's (FPD) market and demand for highly efficient and colored luminescent films have been growing quickly. In this work, thin films were obtained from Pechini's solution by dip-coating. The green films were thermally treated at 873K in order to get ZnO:Eu 1at% thin film. A Schott®glass plate hydrothermally treated was used as substrate. The films have a mosaic shaped feature that was observed by optical microscopy. That feature is a result of substrate thermal treatment. The film deposition decreases the substrate transmittance in the visible range. When the7F0→5L6(392nm) Eu3+transition is excited, it is possible to detect emission from5D0→7FJ(J=1, 2, 3 and 4) transitions. The5D0→7F2transition is also observed by using ZnO excitation wavelengths indicating energy transfer from ZnO to Eu3+ion.
