The phase diagram of a cetyltrimethyl ammonium bromide(CTAB)/n-butanol/n-octane/KNO_ 3-Mg(NO_ 3)_ 2 system was drawn. Nanoparticles of Eu 2-doped KMgF_ 3 were prepared from the quaternary microemulsions of cetyltrimethyl ammonium bromide(CTAB), n-butanol, n-octane and water. The X-ray diffraction(XRD) patterns were indexed to a pure KMgF_ 3 cubic phase. The environmental scanning electron microscopic(ESEM) images show the presence of spherical Eu 2-doped KMgF_ 3 nanoparticles with a diameter of ca. 20 nm. The emission of KMgF_ 3∶Eu 2 nanoparticles peaks at 360 nm. The excitation band was observed at 250 nm with a blue shift of ca. 70 nm compared with that of KMgF_ 3∶Eu 2 single crystal. The preparation method of nano-KMgF_ 3∶Eu 2/PMMA composite films was inquired into.
