A novel green persistent phosphor CdGeO3:Tb3+ is prepared successfully via the traditional solid state reaction method. The phase purity and morphology of CdGeO3:Tb3+ samples are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively.Energy transfer from host to activators Tb3+ occurs efficiently under excitation into the host absorption. CdGeO3:Tb3+ phosphors...
Bi 3+ -doped Zn 2 GeO 4 were prepared by the high temperature solid-state reaction method. The phase purity and crystallinity of Zn 2 GeO 4 :Bi 3+ samples were characterized by X-ray diffraction (XRD). The Photoluminescence and persistent properties of Zn 2 GeO 4 :Bi 3+ phosphors were investigated through the excitation spectra,...
