Ultrafast microwave-assisted synthesis enables phase-pure wurtzite ZnO nanorods within 50 s, delivering uniform morphology, low-defect crystallinity, and preserved wide-bandgap properties for UV optoelectronic applications.

ZnO nanorods (ZnO NRs) are some of the most significant one-dimensional oxide nanostructures because they have a broad direct band gap, a high exciton bind
