A series of CuNa-ZSM-5 zeolites with different Cu/Al and Si/Al rations and CuCaNa- and CuCeNa-ZSM-5 zeolites were prepared by Cu2+ ion exchange from Cu acetate and Cu chloride solutions in order to investigate the complexation of the Cu ions in hydrated and dehydrated zeolites. VIS-NIR d-d spectra of the Cu2+ ions in hydrated and Cu+ luminescence spectra of the dehydrated zeolites were used to indicate the coordination of the Cu ions in the zeolites.
