Cobalt thin films on gold:A new reference material for the quantification of cobalt phthalocyanine and cobalt porphyrin modified gold electrodes with synchrotron radiation micro X-ray fluorescence spectroscopy

摘要

New reference materials consisting of cobalt thin films on gold were prepared by sputter deposition.The thickness and homogeneity of the films were characterized using synchrotron radiation micro-XRF.The samples can be used as reference materials to quantify cobalt phthalocyanine and cobalt porphyrin modified gold electrodes which have been analyzed with synchrotron radiation micro-XRF.
