BUONO-CORE, G.E. et al. USE OF A SINGLE-SOURCE MIXED-METAL PRECURSOR FOR THE PHOTODEPOSITION OF Pd/Ni OXIDES THIN FILMS. Bol. Soc. Chil. Quím. [online]. 2002, vol.47, n.4, pp. 495-500. ISSN 0366-1644. http://dx.doi.org/10.4067/S0366-16442002000400021.
Irradiation of thin films of a polyketonate Pd/Ni heteronuclear complex, PdNi(DBA)2 [DBA = dibenzoylacetone)], produced uniform films containing Pd and Ni as shown by EDAX analysis. The X-ray powder diffraction spectrum showed peaks associated with elemental Pd and NiO. The morphology of the films was examined by SEM measurements showing a uniform granular surface with particle sizes of 100 nm or less. The XPS results show that the ratio of Pd/Ni (1:17) present in the film does reflect the stoichiometry in the starting complex. The large amount of carbon (52 %) detected on the surface of the film may be due to the presence of phenyl rings in the precursor complex.
