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 mole % 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 pump power. Consequently, Yb3+/Pr3+ doped TeO2-ZnO-BaO glasses could be used as functional optical materials for solid-state lighting applications.Keywords : Downconversion, Tellurite glasses, Color parameters, Lighting
