The glass transition temperature (T{sub g}), density, refractive index, Raman scattering spectra, and X-ray photoelectron spectra (XPS) for xZnO-yBi{sub 2}O{sub 3}-zB{sub 2}O{sub 3} glasses (x=10-65, y=10-50, z=25-60 mol%) are measured to clarify the bonding and structure features of the glasses with large amounts of ZnO. The average electronic polarizability of oxide ions ({alpha}{sub O2-}) and optical basicity ({Lambda}) of the glasses estimated using Lorentz-Lorenz equation increase with increasing ZnO or Bi{sub 2}O{sub 3} content, giving the values of {alpha}{sub O2-}=1.963 A{sup 3} and {Lambda}=0.819 for 60ZnO-10Bi{sub 2}O{sub 3}-30B{sub 2}O{sub 3} glass. The formation of B---O---Bi and B---O---Zn bridging bonds in the glass structure is suggested from Raman and XPS spectra. The average single bond strength (B{sub M---O}) proposed by Dimitrov and Komatsu is applied to the glasses and is calculated using single bond strengths of 150.6 kJ/mol for Zn---O bonds in ZnO{sub 4} groups, 102.5 kJ/mol for Bi---O bonds in BiO{sub 6} groups, 498 kJ/mol for B---O bonds in BO{sub 3} groups, and 373 kJ/mol for B---O bonds in BO{sub 4} groups. Good correlations are observed between T{sub g} and B{sub M---O}, {Lambda} and B{sub M---O}, and T{sub g} and {Lambda}, proposing that the average single bond strength is a good parameter for understanding thermal and optical properties of ZnO---Bi{sub 2}O{sub 3}---B{sub 2}O{sub 3} glasses. -- Graphical abstract: This figure shows the correlation between optical basicity {Lambda} and average single bond strength B{sub M---O} in ZnO---Bi{sub 2}O{sub 3}---B{sub 2}O{sub 3} glasses. A good correlation is observed, proposing that the average single bond strength is a good parameter for understanding optical properties of ZnO---Bi{sub 2}O{sub 3}---B{sub 2}O{sub 3} glasses.
