Clean Synthesis of ZnO-Au Nanoconjugate Inks for Bandgap Tuning Applications

This paper introduces a method for the scalable production of pristine nanoinks using ZnO-Au nanoconjugates, achieved through pulsed laser ablation in liquid (PLAL). This approach to nanoink synthesis offers adaptability in creating conjugates with adjustable bandgaps, suitable for direct inkjet printing applications. Our research is particularly centered on the clean fabrication of ZnO-Au conjugate nanoinks, investigating the capacity for bandgap modification in ZnO through the incorporation of gold nanoparticles of diverse sizes. The method highlights the crucial function of controlled laser ablation as a key technique for achieving precision and consistency in nanoparticle creation, thereby guaranteeing the superior quality and uniformity of the ZnO-Au nanoinks produced. Employing comprehensive characterization techniques, including SEM and EDS, we present the properties of the synthesized nanoconjugate inks.
