The advances of EPR spectroscopy for the detection of activators as well as determining their local structure in the crystalline phase of glass ceramics is considered. The feasibility of d-element (Mn²⁺, Cu²⁺) and f-element(Gd³⁺, Eu²⁺) ion probes for the investigation of glass ceramics is discussed. In the case of Mn²⁺, the informationis obtained from the EPR spectrum superhyperfine structure, for Gd³⁺ and Eu²⁺ probes – from the EPR spectrum fine structure, whereas for Cu²⁺ ions the changes in the EPR spectrum shape could be useful. The examples of EPR spectra of the above-mentioned probes in oxyfluoride glass ceramics are illustrated.
