| 摘 要： | We investigated the thermal stability and spectroscopic properties of the 1.53 μm emission from 4I13/2→4I15/2 transition of Er3 ions in Er3 /Yb3 -codoped Ga-Bi-Pb-Ge heavy metal oxide glass for use in broadband fiber amplifiers. It was noted that the addition of GeO2 ef-fectively enhanced the thermal stability of the heavy metal oxide glass studied. The emission peak located at approximately 1530 nm with a full width at half-maximum of approximately 58 nm. The measured lifetime and the calculated emission cross-section of this transition were ～3.2 ms and ～10.3×10–21 cm2, respectively. As a result, Ga-Bi-Pb-Ge heavy metal oxide glasses were assumed to be potential host material for the 1.53 μm broadband optical fiber amplifiers.
