Our studies were focused on the inkjet-printing of aluminum-doped zinc oxide (AZO) nanostructures. This additive fabrication technique is based on the printing of an active material by tiny MEMS-jets onto rigid and flexible substrates for the preparation of functional material thin films. In our case, AZO platelets and isotropic spherical AZO nanoparticles were synthesized by aqueous coprecipitation at the GREMAN laboratory. Then, the preparation of the solvent-based ink was performed at the ICMN laboratory with the control of the viscosity, ink stability and nanoparticles dispersion. We also analyzed the influence of the particle shape on the optical (by an ellipsometer), electrical (by the 4 point probe method, electrical impedance), morphological (by the SEM analysis) and structural properties (by the DRX analysis) of the thin films. These structures turn out to be very promising candidates for sensor applications due to their good transparency, conductivity and non-toxicity.
