From material points of view with wide area application, development of n- or p-type semiconductors is one of the key technologies for p-n junction based devices as diodes, transistors, and light emitting diodes. As our interest in ZnO NPs suited for inkjet printing, we have successfully synthesized well dispersed uniform ZnO NPs with particle size 10±2nm by solution process. As-synthesize ZnO NPs were investigated with details in terms of its structural and optical characterization. Moreover, as-synthesized ZnO NPs were formulated as an ink using mixed solvents of DI water, ethanol, IPA and EG. Further, using as-formulated ZnO ink we have successfully demonstrated jetting and writing of ZnO pattern lines on Si/SiO2 substrate at room temperature. Moreover, microwave-assisted annealing (MAA) effect on printed line feature has also been discussed. |
