Photoluminescence Study of Europium-Doped ZnO Nanostructures

Zinc oxide (ZnO) is a widely studied semiconductor material due to its unique physical and chemical properties. It is a promising candidate for various electronics, optoelectronics, and energy harvesting applications. Photoluminescence, the emission of light upon excitation by photons, is crucial in studying europium-doped zinc oxide (ZnO) nanostructures. The incorporation of europium, a lanthanide element, into the ZnO semiconductor matrix has garnered significant attention due to the remarkable optical characteristics of this combination. Various factors, including the crystallographic properties, defect structure, and material morphology, influence the photoluminescence behavior of europium-doped ZnO nanostructures. This paper presents a review of the photoluminescence study of europium-doped ZnO nanostructures.
