Emissions of europium(Ⅱ) and europium(Ⅲ) have been observed in SrMgF₄:Eu and SrMgF₄:Eu,Ce phosphors which are synthesized in Ar flow.It is notable that the intensity of the ESR peaks corresponding to Eu²⁺ is increased when cerium ion is incorporated which can be explained by electron transfer mechanism.
