Abstract

In this article, to investigate the luminescent properties of rare-earth ion doped and transition metal doped cuspidine glasses, the transparent Ce³⁺ doped and Ce³⁺/Mn²⁺ co-doped 3CaO-CaF₂-2SiO₂ glasses were prepared. The luminescence emission spectra, excitation spectra and luminescence decay curves were recorded and analyzed. The tunable broadband emission was obtained from Ce³⁺ doped 3CaO-CaF₂-2SiO₂ glasses. With the increasing of Ce³⁺ contents, the luminescence intensity shows concentration quenching when the doping concentration is 0.5 mol% while the lifetime decrease. The energy transfer between Ce³⁺ and Mn2+ is confirmed in Ce³⁺/Mn²⁺ co-doped 3CaO-CaF₂-2SiO₂ glasses from emission spectra and decay curves of the co-doped glasses samples. The emission color of Ce³⁺/Mn²⁺ co-doped 3CaO-CaF₂-2SiO₂ glasses can be tuned from the blue to purple by adjusting the concentration of Mn²⁺ ions.
