The crystal qualities, grain size, diameter, PLX3397 purchase and optical bandgap of the ZnO NRs were affected by the type of solvent used in the ZnO seed layer preparation. The ZnO NRs that were synthesized with the use of 2-ME, a solvent, exhibited the most improved results, in terms of structural and optical properties; these ZnO NRs showed the smallest grain size, smallest crystallite size, and
highest bandgap values. The method developed in this study provides a simple and low-cost approach to fabricate ZnO NRs with the desired properties.
