摘要：

Mn2+-doped Zn2SiO4 phosphor films were deposited on silicon and quartz glass substrates by sol-gel method (dip-coating). The variations of sol viscosity with time, him thickness with the number of layers were investigated in the Zn2SiO4:Mn system. The results of XRD and IR showed that the Zn2SiO4:Mn films remained amorphous below 700 degrees C and crystallized completely around 1000 degrees C. From AFM studies, it was observed that the grains of 0.5-0.8 mu m in size packed closely in Zn2SiO4:Mn films, which were uniform and crack free. The luminescence properties of Zn2SiO4:Mn films were characterized by absorption, excitation and emission spectra, as well as luminescence decay. (C) 1999 Published by Elsevier Science S.A.
