Abstract:

KMnF3 and europium-doped KMnF3(KMnF3:Eu) were prepared via a simple molten salt synthesis(MSS) method and the samples were characterized by X-ray diffraction and photoluminescence spectra. Fluorescence spectrum analysis indicates that three luminescence centers(Mn2+, Eu2+ and Eu3+) coexist in KMnF3:Eu system. By changing the molar fraction of Eu, the luminous intensities of Mn2+, Eu2+ and Eu3+ were further discussed.
