Tb³⁺-doped fluorophosphate glasses with the composition of P₂O₅–K₂O–SrF₂–Al₂O₃–x Tb₄O₇ (where x = 0.1, 0.5, 1.0, 2.0 and 4.0 mol%) were prepared by a conventional high temperature melt quenching technique and characterized through absorption, emission, excitation and decay measurements. From the emission studies, a strong green emission at around 546 was observed, which corresponds to the ⁵D₄ → ⁷F₅ transition of Tb³⁺ ion. Green/blue intensity ratios (I_G/I_B) were evaluated as a function of Tb³⁺ concentration and vice versa. Higher I_G/I_B intensity ratio confirms the higher covalency between Tb–O bond and higher asymmetry around the Tb³⁺ ions in the present fluorophosphate glasses. The decay curves for the ⁵D₄ level of Tb³⁺ ion were measured and found that they exhibited single exponential nature irrespective to the dopant concentration. The experimental lifetime was determined using single exponential fitting and found that it increased from 2.65 to 2.95 ms when Tb³⁺ concentration increased from 0.1 mol% to 4.0 mol%. The derived properties were compared to the other Tb³⁺-doped glasses in order to see the potentiality of the material for visible laser gain media at 546 nm.
