| Abstract Scope |
Metal and metal oxide nanoparticles and quantum dots have potential applications in transistors, displays, photovoltaics, batteries, sensors, etc. We developed transparent silver inks based on silver-ethanolamineformate-complex, utilized them for fabricating conductive circuits and electrodes. As-formulated transparent Ag ink showed long-lasting stability without the occurrence of turbidity. The nozzle-jet printed Ag features on flexible substrates (PET and PI) yielded remarkable conductivities close to bulk silver after annealing at 70–100 °C. Metal-cation-doped ZnO (mc:ZnO) QDs synthesized at a low temperature with varying dopant concentration were utilized to formulate QDs inks for applications in organic and quantum dot LEDs. Optoelectronic properties of the QDs inks were examined with bandgap engineering as a function of dopant concentration. The mobility and defect density of Ba:ZnO and Mn:ZnO increase and decrease, respectively, with dopant concentration. By contrast, Si:ZnO and Al:ZnO show a decrease in mobility and an increase in defect density with dopant concentration. |
