中文摘要：

通过溶胶．凝胶法在PDP绿色荧光粉BaMgSrAl10O17：Mn的表面包覆纳米尺度的Al2O3-SiO2复合膜，并对包覆机制进行了探讨。通过ICP—AES、SEM、FT-IR和XRD对包覆过程及包覆结果进行了表征。

英文摘要：

A coating on PDP phosphor by a thin and homogeneous layer of nano-scale colloidal Al2O3 and SiO2 using the sol-gel method was investigated and the mechanism was studied. ICP-AES, SEM, FT-IR and powder XRD were employed to characterize the coating.
