Abstract Measurements of the electron spin resonance spectrum have been made in a Gd3+ doped lithium-aluminium-silicate glass at various stages during the crystallization of the glass. The crystallization was induced by heat-treatment at various temperatures and took place either from the surface or from nucleation centres produced by the presence of TiO2 in the glass. The changes in the resonance spectra have been interpreted in terms of the stability of the gadolinium sites. In the presence of titanium, it is suggested that complexes are formed in the glass which involve both titanium and gadolinium ions. Supporting measurements show that the presence of these complexes is also detectable from the more conventional structural and thermal characterization of the glasses.
