Electrochemical Growth of Eosin Y/Manganese Doped ZnO as Hybrid Films and Nanowires

Mariana Sima , Teodor Visan , Elena Matei , Florica Ungureanu , Ionut Enculescu and Marian Sima


The electrodeposition process of Eosin Y/ZnO: Mn as films and nanowires performed using a solution containing zinc and manganese nitrates + lactic acid mixture was studied by linear voltammetry. The films and wires grown by polarization at −1.1 V/SCE electrode potential were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy (XPS). Additionally, the Eosin Y presence was evidenced by optical measurements as absorption and photoluminescence spectroscopy. The manganese content in films depends on the nature of support electrode used. On the other hand, the presence of Eosin Y species in the deposition bath increased significantly the manganese concentration in the ZnO: Mn nanowires electrodeposited at −1.1 V/SCE.
