Glass transition temperatures T-g and Raman spectra of KPO3.Lni(PO3)(3
) (Ln = rare earth ion) glasses were measured for all rare earth membe
rs (except Pm). From the series behavior of the T-g and Raman data, it
is concluded that the coordination number around rare earth ions chan
ges, probably from nine to eight, in the middle of the rare earth seri
es.
