摘要：

Optical basicities (Γ) for Cs2O + B2O3 and Li2O + B2O3 glasses have been measured as a function of glass composition, using Tl+, Pb2+ and Bi3+ probe ions. The three probe ions register different values of Γ for glasses of given composition (and also for pure B2O3 glass and water). The divergence decreases as the alkali metal ion size decreases. For the Li2O + B2O3 glasses, ideal (calculated) optical basicities agree within experimental precision with experimental values registered by Pb2+ (ΓPb2+) up to about 15 mol% Li2O. For higher Li2O contents, and for the Cs2O + B2O3 glasses, ideal optical basicities agree less well with ΓPb2+, but show similar trends with composition to those shown by ΓPb2+. © 1979.
