Photoluminescent, optical and magnetic property characterization of green chemistry method prepared calcium doped ZnO nanoparticles

초록

Employing a green synthesis technique, we produce cost-effective zinc oxide nanoparticles and calcium-doped zinc oxide nanoparticles by utilizing Citrus sinensis fruit extract as an efficient reducer and encapsulating agent. XRD analysis confirmed a wurtzite structure for the as synthesized ZnO and calcium doped ZnO nanoparticles. Oxidation states and quantification of the element on the surfaces of pure and Ca-ZnO was achieved through XPS investigations. Nano-flakes structures of the synthesized samples are prominently depicted in the HR-SEM image, providing visual insight into their morphology. The elemental analysis and their quantity were discerned using EDX spectrum. Moreover, Magnetization- Field (M-H) hysteresis curves demonstrated diamagnetic behavior at room temperature.
