Facile Synthesis of Monodisperse KY3F10 Nanospheres

Abstract

Highly uniform and monodisperse KY3F10 nanospheres, with an average diameter of 300 nm, have successfully prepared through a simple solution method employing the reaction of Ln(NO3)3 and KBF4 under ambient conditions, without any template or surfactant. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence (PL) spectra were used to characterize the samples. The SEM images illustrate that these spheres were actually composed of randomly aggregated nanoparticles.
