Luminescence Properties of Green Phosphor Ca₂Ga₂(Ge_1-xSi_x)O₇:y%Eu²⁺ and Application.

ABSTRACT: Rare earth luminescent materials demonstrate significant advantages in lighting and energy saving, and detection etc. In this paper, a series of Ca₂Ga₂(Ge_1-xSi_x)O₇:y%Eu²⁺ phosphors were synthesized by high-temperature solid-state reaction and characterized by X-ray diffraction and luminescence spectroscopy methods. The powder X-ray diffraction patterns reveal that all the phosphors are isostructural with a space group of P4¯21m. The excitation spectra of Ca₂Ga₂(Ge_1-xSi_x)O₇:1%Eu²⁺ phosphors exhibit significant overlapping of the host and the Eu²⁺ absorption bands, which facilitates Eu²⁺ absorbing the energy to increase its lu
