AbstractThe spectroscopic properties and thermal stability of Er2O3 doped Bi2O3-B2O3-Na2O glasses are investigated experimentally. A close correlation is observed between the B2O3 content and the spectroscopic properties such as Judd-Ofelt intensity parameters Omega(t) (t=2,4,6), emission spectra, and lifetime of I-4(13/2) level of Er3+. The value of Omega(6) increases with an increase of B2O3 content, which is attributed to the decrease of the covalency of Er-O bond in terms of the glass microstructure and electronegativity theory. The emission spectra of I-4(13/2)-->I-4(15/2) transition broadens as a consequence of the enhancement of the inhomogeneous distribution of Er3+ sites when increasing B2O3 content. The lifetime of I-4(13/2) level of Er3+ in bismuth-based glass, compared with those in other glasses, is relative low due to the high-phonon energy of the B-O bond, the large refractive index of the host, and the existence of OH- in the glass. In addition, the glass stability is improved in which the substitution of B2O3 for Bi2O3 strengthens the network structure. The suitability of bismuth-based glass as a host for Er3+ doped for a broadband amplifier and its advantages over other glass hosts are also discussed. (C) 2003 American Institute of Physics.
