A new glass of Gd₂O₃–B₂O₃–SiO₂–Na₂O–Er₂O₃ system is prepared and the formation range of the glass is experimentally obtained. Excellent thermal stability of the glass has been demonstrated using differential thermal analysis. Effects of the B₂O₃ content on the infrared spectral properties such as the 1.5 μm emission bandwidth and the Judd–Ofelt parameter Ω_t (t = 2, 4, 6) of Er³⁺ ions in the glass has been observed. The glass exhibits a large integrated emission cross sections for the 1.5 μm emission band. The Er³⁺-doped gadolinium borosilicate glass is a great candidate for broadband erbium doped fiber amplifiers.
