1.53 μm photoluminescence from ORMOSIL films doped with erbium complexes

Vinyltriethoxysilane (VTES)-derived ORMOSIL films directly doped with various erbium organic complexes were prepared through a multistep sol–gel process, among which VTES-derived film doped with erbium tris(hexafluoroacetylacetonate)bis(triphenylphosphine oxide) (Er(HFA)3(TPPO)2) exhibited the maximum photoluminescence intensity at 1.53 μm as the erbium doping concentration was 5 mol%. Moreover, the complex erbium tris(8-hydroxyquinolate) (ErQ3) was in situ synthesized successfully in the VTES-derived film as expected and the film also exhibited comparatively intense 1.53 μm luminescence.
