In this research, pure and Ho-loaded zinc oxide nano-rods have been synthesized with the sol-gel spin coating way. The impact of holmium-loading content changed between 0-4 at.% in step of 1 at.% on the structural, vibrational, surface, and optical characters was inquired. The hexagonal ZnO nano-rods with (002) and (101) preferential orientations were seen from SEM and XRD analyses. It was found that the surface character of ZnO nano-rods depended on Ho-loading content. The UV and green emission bands were observed from PL analysis. A blue shift with low-content Ho level was seen from UV/Vis spectrophotometer and PL measurements. The optical band-gap value primarily raised from 3.32 to 3.40 eV for low Ho content, and then, it went down for more Ho loading. The present study gives that the physical features of zinc oxide are greatly healed with holmium loading.
