Mild Hydrothermal Synthesis and Optical Properties of the Complex Fluoride KMgF3 Doped with Eu
摘要:
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 VK color centers; the low emission intensity was due to Eu2+ having transferred part energy to VK color centers.
