Abstract: Er3+-doped bismuth-based glasses with compositions of (50~75)Bi2O3-(20~45)B2O3-5Na2O, 70Bi2O3-(17~25)B2O3-xZrF4-5Na2O, 70Bi2O3-(0~25)B2O3-(0~25)SiO2-5Na2O were prepared. The absorption spectra, emission spectra and lifetime
of 4I13/2 level of Er3+ ion were measured. The mixed former effect was mentioned firstly and its effects on spectroscopic properties of Er3+
ion were investigated. The results indicate that an increase of effective absorption bandwidth, emission cross section, FWHM, and relatively higher
lifetime could be obtained in the bismuth-based glasses through mixed former effects. All these data suggest that Er3+ doped bismuth-based glass is
a good candidate host material for optical amplifiers to realize broadband and high gain amplification.

Key words: mixed former effect, bismuth-based glass, spectroscopy, Er3+ ion
