Dy³⁺ Doping Blue-Green Sr₄Al₁₄O₂₅:Eu²⁺ Phosphor for Enhancing Luminescent Properties and the Mechanism Study

Abstract:

Dy³⁺ doped blue-green Eu²⁺ doped strontium aluminate (Sr₄Al₁₄O₂₅:Eu²⁺) phosphor was prepared using a high temperature solid state method and the influence of the doped Dy³⁺ on the luminescent properties was studied using X-ray diffraction, scanning electron microscopy, fluorescence spectroscopy and a series of other characterization methods. It is found that Dy³⁺ doping can enhance the luminescent intensity and extend the afterglow time. The luminescent mechanism of rare earth ions doped strontium aluminate phosphor was also discussed deeply, the effects of the doping amount on the luminescent properties has been made detailed explanation and description. This work has important theoretical significance for the development of higher brightness and longer afterglow blue-green phosphors.
