This paper reports on the optical spectroscopic properties and thermal stability of Er³⁺-doped antimony-borosilicate glasses for developing 1.5 μm optical amplifiers. Upon excitation at 980 nm laser diode, an intense 1.5 μm infrared fluorescence has been observed with the maximum full width at half maximum (FWHM) of 90 nm for Er³⁺-doped antimony-borosilicate glasses. The emission cross-section and the lifetime of the ⁴I_13/2 level of Er³⁺ ions are 6.3 × 10⁻²¹ cm² and 0.30 ms, respectively. It is noted that the product of the emission cross-section and FWHM of the glass studied is as great as 567 × 10⁻²¹ cm² nm, which is comparable or higher than that of bismuthate and tellurite glasses.
