KMgF₃ doped with Eu was synthesized by mild hydrothermal method at 240℃ for the first time. The excitation and emission spectra of the KMgF₃: Eu²⁺ phosphor were measured. Comparing with the sample synthesized through solid state reaction, the variation in the excitation spectra at 360 nm resulted from the existences of V_K color centers; the low emission intensity was due to Eu²⁺ having transferred part energy to V_K color centers.
