Visible luminescence from Dy3+ doped tellurite glasses

This paper reports on luminescence property of the Dy3+-doped tellurite glasses. The samples are studied by absorption and visible emission spectra. The measured emission spectrum of Dy3+ glass has revealed two main bands at 484 nm (4F9/2→6H15/2) and 574 nm (4F9/2→6H13/2) when pumping with the wavelength of 325 nm. The concentration quenching occurred as Dy3+ concentration increased beyond 2 mol%. The chromaticity coordinates of these samples are close to white light, which implies that the glasses might be a potential candidate for white lighting through an appropriate combination.
