Abstract

Bright green emission is obtained from the Mn2+-doped zinc gallogermanate phosphors. The X-ray diffraction (XRD) and photoelectron spectroscopy (XPS) confirm that zinc gallogermanate so obtained is a solid solution of ZnGa2O4 and Zn2GeO4. The slight change of structure for different sintered hours is reflected in the emission intensity of the Mn2+-doped samples. The low temperature electron paramagnetic resonance (EPR) spectra and PL decay curves are employed to probe into the different luminescence centers in the non-doped and Mn2+-doped zinc gallogermanate phosphors.
