Influence of charge compensators on photoluminescence properties of Sr2CeO4:Eu3+

• A series of SC:0.01Eu3+ materials with different charge compensators were synthesized and further investigated by EDS, XPS, XRD and Rietveld refinements to verify the purity.
• The effects of charge compensators on optical features were systematically studied via the reflectance and photoluminescence spectra.
• The anionic charge compensators, especially F−, greatly enhanced photoluminescence properties, which may provide a novel method to synthesize and improve phosphors.

Presently enormous interest in the modification of photoluminescence properties of Sr2CeO4:Eu3+ with charge compensators has been stimulated. Here we report the effect of charge compensators on optical characteristic of Sr2CeO4:Eu3+ synthesized by altering types of charge compensators and propose the possible explanation. The conclusion is made that anionic charge compensators, especially F−, may provide a novel approach to the development and improvement of the phosphors.
