Paper Abstract

We prepared a sol-gel hybrid material which has low loss near 1.5 μm wavelength using methyltriethoxysilane, vinyltriethoxysilane, and phenyltrimethoxysilane as precursors. Several erbium precursors were used in order to incorporate into the hybrid matrix. Among several Er-doped system, the sol-gel hybrid films doped with ErQ showed a clear photoluminescence at 1.5μm when they were pumped by 477nm light, not a resonant wavelength of Er3+ ions, which is expected to absorb the pump energy and transfer to adjacent Er3+ ions. Indirect excitation mechanism was investigated by photoluminescence excitation measurement using various wavelengths of Ar+ laser. The sol-gel hybrid films doped with ErQ show an efficient indirect excitation of Er3+ luminescence through ligand sensitization.
