Electrodeposition of Lu-Co-Bi Thin Films in an Organic Bath

Abstract

The electrodeposition of Lu-Co-Bi thin films from Lu(III), Co(II), and Bi(III) solutions was studied in nonaqueous dimethysulfoxide (DMSO). Different substrates have been used (platinum and copper), and the effect of them on the electrochemical behavior of the studied ions is shown. The obtained Lu-Co-Bi thin films were subjected to scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction (XRD) analysis. The lutetium content in Lu-Co-Bi thin film increases as the potential was made more cathodic, reaching a maximum value of 26.84 wt %, and then decreases. The films were amorphous. After heat-treatment of crystallization at 520°C for 1 h, the alloy phase of and can be found in the XRD patterns. © 2004 The Electrochemical Society. All rights reserved.
