Cobalt, nickel and copper doped non-stoichiometric cadmium gallate as a prominent magnetic and photocatalytic material

Cobalt, nickel and copper doped non-stoichiometric CdGa2O4 were synthesized via epoxide gel approach. Cubic spinel arrangement of undoped and doped samples was investigated from powder X-ray diffraction pattern and the complete structure analysis was done by using Raman spectroscopy. Additionally, morphology of doped samples was analysed by FESEM images and elemental ratio of these samples have been obtained using Energy Dispersive spectrum (EDS). The oxidation state of doped metal ions was determined by optical and photoluminescence spectroscopy. The magnetic study of the doped samples showed the antiferromagnetic and ferromagnetic behaviour. The variation of band gap in transition metal doped samples has been favourably utilized for the photodegradation studies of aqueous solution of methylene blue and Rhodamine B dye.

Automated summary

Cobalt, nickel, and copper doped non-stoichiometric CdGa2O4 were synthesized and characterized using various techniques. The doped samples showed both antiferromagnetic and ferromagnetic behavior, and the transition metal doping also promoted the photodegradation of methylene blue and Rhodamine B dye.
