Electron spin resonance and optical absorption spectra of Cu2+ ions in Na2SO4-ZnSO4 glasses

Electron spin resonance (ESR) spectra of Cu2+ ion-doped glasses exhibited a pronounced peak at g = 2.07 and a shallow quadruplet at g = 2.35, the latter arising from the hyperfine splitting of g. ESR spectra of Cu2+ ion-doped glasses were also studied by varying the concentration of Cu2+ ion, temper...

Summary:Electron spin resonance (ESR) spectra of Cu2+ ion-doped glasses exhibited a pronounced peak at g = 2.07 and a shallow quadruplet at g = 2.35, the latter arising from the hyperfine splitting of g. ESR spectra of Cu2+ ion-doped glasses were also studied by varying the concentration of Cu2+ ion, temperature and composition of the glasses. The optical absorption spectra exhibited a broad absorption band in the near infra-red region, which is attributed to 2B1g to 2B2g transition. By correlating the ESR and optical absorption data, the bonding orbital coefficients for Cu2+ ions have been evaluated. 34 refs.
