Effects of the B2O3 content on the infrared spectral properties such as the 1.5 m emission bandwidth corresponding to 4I13/2&rarr4I15/2 transition and the Judd-Ofelt parameter t (t = 2  4  6) of Er3+ ions in the glass has been observed. The glass exhibits big integrated emission cross sections for the 1.5 m emission band. Excellent thermal stability of the glass has been demonstrated using differential thermal analysis. The Er 3+-doped lutetium borosilicate glass is a great candidate for broadband erbium doped fiber amplifiers.
