Structural and ESR studies of Cu‐doped ZnO nanostructures

Surface morphology, structural phases, and electron spin resonance (ESR) measurements were performed for Zn1‐xCuxO nanoparticles (x = 0.00, 0.01, 0.02, 0.03, 0.04, and 0.05) synthesized by sol‐gel method. The optimum annealing temperature (600°C) and weight loss was clarified using differential ther...

Summary:Surface morphology, structural phases, and electron spin resonance (ESR) measurements were performed for Zn1‐xCuxO nanoparticles (x = 0.00, 0.01, 0.02, 0.03, 0.04, and 0.05) synthesized by sol‐gel method. The optimum annealing temperature (600°C) and weight loss was clarified using differential thermal analysis (DTA), and thermo gravimetric analysis (TG). By means of X‐ray diffraction (XRD) technique, the phase of the samples was defined as single with ZnO wurtzite hexagonal structure and proofed by Rietveld analysis for Zn0.98Cu0.02O sample with calculating c/a rate. Spherical shape random particle distributions were observed in all scanning electron microscope (SEM) measurements. ESR measurements were conducted for all samples and g‐value and ΔH (G) values were calculated and correlated from ESR measurements.
