Abstract

A novel Ce

/Eu

co-activated Ca

phosphor was synthesized by traditional solid-state reaction. The phosphors were characterized by X-ray diffraciton (XRD) and fluorescence spectrophotometer (PL). XRD patterns reveal that the samples maintain Ca

single phase after doping Ce

and K

ions. The emission spectra under 355 nm excitation show the typical broad band of Eu

peaking at about 505 nm (5d-4f). The emission could be greatly enhanced through doping Ce

and K

in Ca

:Eu

phosphors. K

ions could be used as charge compensation in Ca

:Eu

phosphors. When the mole fractions of Ce

and K

are 1%

the emission intensity reach the maximum

which is about 168% of that of the sample without doping Ce

or K

. And the critical distance is calculated to be about 2.535 nm by the spectra overlap method.
