摘要

New chemical synthesis was successfully applied to obtain YF_3: 1% Er nanocrystals. This method is a thermal decomposition of nitrates and acetates, preceded by solution displacement reaction. The sample was characterized by the following methods: X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and magnetic susceptibility thermal dependence measurements. The obtained compound crystallizes in orthorhombic structure. Both, chemical composition determined by XPS and magnetic measurements prove to be in agreement with nominal formula. The SEM images show the nanometric size of the grains. The chemical shift of the XPS lines and wide energy gap indicate the covalent type of chemical bonds.
