摘要/Abstract

摘要： The phase diagram of a cetyltrimethyl ammonium bromide (CTAB)/n-butanol/n-octane/KNO₃-Mg (NO₃)₂ system was drawn. Nanoparticles of Eu²⁺ -doped KMgF₃ 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 KMgF₃ cubic phase. The environmental scanning electron microscopic(ESEM) images show the presence of spherical Eu²⁺ -doped KMgF₃ nanoparticles with a diameter of ca. 20 nm. The emission of KMgF₃: Eu²⁺ 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 KMgF₃: Eu²⁺ single crystal. The preparation method of nano-KMgF₃: Eu²⁺/PMMA composite films was inquired into.
