Abstract

Abstract: Cerium ion activated ZnAl2 O4 phosphors were first time prepared by efficient and simple biogenic synthesis approach using aloe vera extract. The prepared samples were characterized by x-ray diffraction (XRD), ultraviolet visible spectroscopy (UV), and photoluminescence technique (PL). From XRD technique, the crystal structure of the prepared Ce 3+ doped ZnAl2 O4 phosphors was calculated and it was a cubic structure. The optical band gap energies of ZnAl2O4 host and Ce 3+ doped ZnAl2 O4 were calculated using the UV spectroscopy technique. The PL spectra were showed the maximum intensity for Ce3+ doped ZnAl2 O4 at 530 nm and 598 nm under 398 nm excitation wavelength. The CIE color co-ordinates of the Ce 3+ doped ZnAl2 O4 are calculated using radiant imaging color calculator program refer to the 1931 CIE Standard Source C (illuminant Cs (0.3101, 0.3162)).
