Abstract:
1. A method for preparing silica-dysprosium oxide core-shell nanoparticles, comprising: mixing ethyl silicate, n-butanol, ethylenediamine, and distilled water in the presence of ultrasonic radiation to prepare silica nanoparticles; isolating the silica nanoparticles; mixing the isolated silica nanoparticles, an acid, n-butanol, and dysprosium oxide in the presence of ultrasonic radiation to prepare silica-dysprosium oxide core-shell nanoparticles; and isolating the silica-dysprosium oxide core-shell nanoparticles.
