The main goal of this paper is to generate a warm white light through gamma-irradiated Tb3+/Sm3+-codoped oxyfluoride aluminoborate glasses under 387 nm excitation xenon lamp. The transparent Tb3+/Sm3+-codoped oxyfluoride aluminoborate glass samples were prepared by meltquenching technique. The energy transfer mechanism between Tb3+ and Sm3+ ions with an emphasis on the role of Al2O3/Al3+ is systematically studied before and after gamma-irradiation. The characteristics of white light emission defined by chromaticity color coordinates and correlated color temperature are evaluated. In the present glass systems, the tuning of cold-to-warm white light as a function of Al2O3 and gamma-irradiation is demonstrated.
