Abstract

Downconversion processes which include visible and near-infrared luminescence at high energy excitation have been investigated in Yb³⁺/Pr³⁺ doped TeO₂-ZnO-BaO glasses. The decrease of the DC emission intensities of Pr³⁺ ions with increasing mol% amount of Pr³⁺ ions is attributed to the concentration quenching. The CIE chromaticity coordinates of the perceived emission of Pr³⁺ ions shifted from orange to the red region depending on the increase in the pumping power. Consequently, Yb³⁺/Pr³⁺ doped TeO₂-ZnO-BaO glasses could be used as functional optical materials for solid-state lighting applications.
