Active glasses as the luminescent sources of radiation for sensor applications

The article presents physicochemical, thermal and spectroscopic properties of two different glass systems: TeO -GeO -PbO-PbF - BaO-Nb -LaF and SiO -Al -Sb , co-doped with Yb /Tm ions. Blue upconversion luminescence at a wavelength of 478 nm corresponding to the thulium transition was observed under...

Description
Summary:The article presents physicochemical, thermal and spectroscopic properties of two different glass systems: TeO -GeO -PbO-PbF - BaO-Nb -LaF and SiO -Al -Sb , co-doped with Yb /Tm ions. Blue upconversion luminescence at a wavelength of 478 nm corresponding to the thulium transition was observed under 976 nm pump radiation in both of the co-doped glasses. This indicated the existence of efficient Yb ⇥ Tm energy transfer via three-photon absorption mechanism. Thermal and optical results substantiate the claim for practical applicability of the manufactured glasses in design of optical fiber sources.
