Co-doped zinc oxide nanoparticles as eco-friendly green ceramic pigment

In this study, Co-doped zinc oxide nanoparticles were synthesized by combustion method and Glycine as fuel. As-prepared powders were characterized by XRD, SEM, TEM and spectrophotometer. Color properties of the synthesized samples have been investigated using the CIELAB coordinates and spectral reflectance. XRD patterns indicated that combustion reaction by glycine as fuel caused the formation of pure ZnO phase. SEM pictures showed the formation of porous spongy morphology which is related to large amount of exhaust gases from combustion reaction. The TEM images of Zn-CoO powders shows particle size of about ۴۰ nm Colorimetric results also indicated a broad reflectance band around ۵۴۰ nm (green region) for the as-prepared powders.
