Abstract
In this work, thermal and luminescent properties of lithium-borate glass and glass-ceramics co-doped with Eu3+/Dy3+ and Eu3+/Tb3+ ions have been investigated. The parent borate glasses were synthesized by the standard melt-quenching method. The amount of crystallites grown in the glass was controlled by the appropriate choice of annealing time and temperature. Stronger luminescence has been observed for glass-ceramics than for glass in each case. Zinc lithium borate (LiBZnF) glass-ceramics co-doped with 0.25Eu and 0.5Tb had the strongest luminescence under 388 nm laser excitation. The energy transfer mechanisms between Tb3+ and Eu3+ ions and Dy3+ and Eu3+ ions were discussed. Also, the influence of the molar ratio of active ions on the colour coordinates (CIE-1931) have been investigated.
