This study was conducted to analyze the effect of variations in annealing temperature of 200˚C, 250˚C, 300˚C, 350˚C and 400˚C with Boron doped of 1% to the morphology of the resulted ZnO nanorods. Samples were characterized by using the methods of Field Emission Scanning Microscope (FESEM) and Energy Dispersive X-Ray (EDX). FESEM characterization results showed that Boron-doped ZnO nanorods grew up on the surface of the FTO having hexagonal cross-sectional shape with a diameter in the range of 100- 500 nm. The variation of annealing temperature produced ZnO nanorods with various diameters. The best homogenity level sample is for 300˚C. The cross-sectional FESEM images showed that nanorods ZnO height generated increased with increment of annealing temperature. EDX spectra showed that by increasing annealing temperature, the percentage of the number of atoms and weight of boron increased.enNanorod Zink Oxide (ZnO),dopeddopedFESEMEDXstudent Paper Post Degree
