| Abstract: | Successive ion layer adsorption and reaction (SILAR)
technique was implemented to synthesize
multilayer thin films of Co(II)- and Zn(II)-8-hydroxyquinolate nanoparticles.
Two different approaches have been applied and compared for the formation of
the thin films. The first approach is based on SILAR of Co(II)-(8HQ)2 (8HQ = 8-hydroxyquinoline) layer
followed by Zn(II)-(8HQ)2, while the second is directed toward
simultaneous SILAR of the two
metal complexes. The two studied metal ions behave independently in their
reaction with 8HQ with a molar stoichiometric ratio of 1:2 in the two metal
complexes. Mixed metal complexes have not been identified under the
experimental conditions. Under the same experimental conditions, Zn(II)-(8HQ)2
complex has been found to proceed four times faster than Co(II)-(8HQ)2
complex. The percentage compositions of the deposited thin film nanoparticles
of Co(II)-(8HQ)2 and Zn(II)-(8HQ)2 complexes have also
been tuned. Multilayer deposited and synthesized nanoparticles of Co(II)-(8HQ)2
and Zn(II)-(8HQ)2 complexes thin films have been monitored,
and evaluated by using electron impact-mass spectra, scanning electron
microscope, thermal analysis and elemental analysis. |
