dc.description.abstract | In this work, nanostructured ZnO powders were fabricated by simply submerging eggshell membranes (ESMs) in a precursor solution. The biomimetization of the ESMs was studied with 0.25M aqueous solutions of three different precursors (zincacetate, zincnitrate and zincchloride). The powders obtained by biomimetization were compared with powders obtained by the precipitation method with identical precursor solutions. These powders were characterized using transmission electronmicroscopy (TEM), scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS), diffuse reflectance spectroscopy (DRS), photoluminescence (PL), spectroscopy and X-raydiffraction (XRD). The results showed the formation of zincite phase for all samples. The biomimetized samples prepared with zincacetate and zincnitrate successfully replicated the ESM morphology with nanometric crystallite sizes. The optical bandgap of biomimetized and precipitated samples presented little variation (3.25 eV), but the photoluminescence spectrum revealed distinct emission for the biomimetizated samples attributed to crystalline defects. | es_ES |
