چکیده انگلیسی
Eu2+ and Mn2+ co-doped calcium aluminate silicate chloride phosphors with the chemical composition of Ca3Al2Si2O8Cl4:Eu2+, Mn2+ have been prepared by a solid-state method, and their luminescence properties have been investigated by tuning the En2+/Mn2+ ions concentration. The phase formation and microstructure of Ca3Al2Si2O8Cl4:Eu2+, Mn2+ phosphors have been illuminated by XRD and SEM analysis. Photoluminescence (PL) spectrum reveals that Ca3Al2Si2O8Cl4:Eu2+ exhibits a strong blue emission band centered at 431 nm, while Ca3Al2Si2O8Cl4:Eu2+, Mn2+ can emit bluish-white light by adjusting the Mn2+ content appropriately. The energy transfer mechanism involving Eu2+–Mn2+ have also been investigated.
