Nanocrystalline Eu-doped Zinc aluminate spinel was produced by a combustion method. Different methods, including X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), and photoluminescence spectroscopy, were used to examine the prepared spinel type ZnAl2O4 ceramic material and characterize its structural, morphological, and photoluminescent properties. The formation of a pure phase with a spinel structure and the space groupfd3 ̅m is confirmed by the zinc aluminate material's X-ray diffraction pattern. Scan and transmission electron microscopy were used to further establish the average surface structure and crystalline size. The PL spectra show the strongest emission at 616 nm corresponds to the 5D0 → 7F2 transition of Eu3+. Photometric parameters like CIE coordinates and CCT values show that prepared phosphor that gives off a bright red light is used in the display and lamp industries.
