Synthesis of ZnO:C composite material via spray pyrolysis and thermolysis of poly(furfuryl) alcohol
Zinc oxide/carbon composite was synthesized on stainless steel and glass via spray pyrolysis for the ZnO layer and thermolysis for the C layer. Two sets of samples were made, one as the control and the other annealed at 700oC. Raman spectroscopy confirms the deposition of ZnO and carbon, albeit disordered; SEM allowed the estimation of the thickness of the films, which is 1.06 µm; and UV-Vis indicated that the annealed samples have higher transmission and a bandgap closer to the theoretical value; which is reflective on the quality of the deposited films.
