A series of Er 3+ -doped 50Bi 2 O 3 -(50-x)B 2 O 3 -xGeO 2 +0.5 wt% Er 2 O 3 (x ΒΌ 0, 5, 10, 15, 20 mol%) glasses were prepared. The thermal stability, absorption spectra, emission spectra and lifetime of the 4 I 13/2 level of Er 3+ ions were measured and studied. It is found that the absorption cros
