Abstract

In the article the glass with molar composition of 75TeO₂-20ZnO-5Na₂O co-doped with Yb³⁺/Tm³⁺/Ho³⁺ ions was fabricated by typical melt-quenching technique. Multicolour up-conversion emission at the wavelengths of 479 nm (blue), 546 nm (green) and 650 nm (red) corresponding to transitions ¹G₄ →³H₆ (Tm³⁺), ⁵F₄→⁵I₈ (Ho³⁺) and ⁵F₅→⁵I₈ (Ho3+), respectively have been observed under infrared excitation (λexc = 980 nm) at room temperature. Influence of molar ratio of active ions on the colour coordinates (CIE-1931) have been investigated.
