Hydrothermally grown ZnO nanorods (NRs) are subjected to stepwise annealing, with steps ranging from zero to three. This method allows for precise control over the length, diameter, and number of defects in the ZnO NRs. Stepwise annealing offers a cost-effective approach to fabricating high-performance optoelectronic devices using ZnO NRs.
