摘要：

The glass substrates doped with Ag nanoparticles (NPs) were fabricated by the field-assisted thermal diffusion (FATD) process. The Er3+/Yb3+ co-doped tellurite thin films were deposited on these substrates via nonhydrolytic Sol-Gel method. It was found that the luminescence of the thin film was significantly enhanced by the Ag NPs embedded in the glass substrate. The distribution of Ag in the substrate after FATD process was calculated by numerical simulating on base of Fick's first and second law, Ohm's law and Poisson equation. The enhancement factor increased with the increase of concentration and diameter of Ag NPs near the glass surface. When the total amount of NPs decreased and the thickness of space-charge layer increased, the enhancement effect became weak. In addition, besides the Ag NPs near the glass surface the Ag NPs far from the glass surface could also contribute to the luminescence enhancement.
