•Strong influence from byproducts to the final nanoparticle morphology.•The effect of purifying and post-annealing treatment increases the ZnO nanoparticle size.•The different reducing agent on the reaction process, plays an important role on the final product and the photoluminescence emission. In this article, zinc oxide green synthesis was made using lemon juice and commercial limonene as a reducing agent. The effect of byproducts concentrations on the final morphology, size and photoluminescence properties is reported. From X-ray diffraction patterns, a slight difference is noticed between one to another route, like the average size difference is noticed, the presence of byproducts in lemon juice contrary to the results obtained by limonene route. The photoluminescence spectra is analyzed, shows a major different intrinsic defects contribution strong influences the emission in lemon juice based nanoparticles meanwhile the when limonene is used, the emission is influenced due to the presence of fewer defects, in addition, morphology is particularly affected probably by the presence/removal of byproducts and the post-synthesis treatment, the shape evolution was observed by scanning electron microscopy characterization. A supplementary energy dispersive spectroscopy elemental composition analysis to identify the byproducts shown in X-ray diffraction in both methods was done.
