The article presents physicochemical, thermal and spectroscopic properties of two different glass systems: TeO_2-GeO_2-PbO_-PbF_2- BaO_-Nb₂O_5-LaF₃ and SiO_2-Al₂O_3-Sb₂O₃, co-doped with Yb³⁺/Tm³⁺ ions. Blue upconversion luminescence at a wavelength of 478 nm corresponding to the thulium ¹G₄ ⇥³H₆ transition was observed under 976 nm pump radiation in both of the co-doped glasses. This indicated the existence of efficient Yb3+ ⇥ Tm³⁺ 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.
