Abstract
• CeF 3 nanoparticles are synthesized by pulsed electron beam evaporation in vacuum. • Received a mesoporous paramagnetic cerium trifluoride nanopowder with a high specific surface. • Comparison of the magnetic response of nanoparticles of fluoride and cerium oxide with each other. The method of pulsed electron beam evaporation (PEBE) in vacuum was first used to obtain CeF 3 nanopowder (NP). During NP production, a high evaporation rate of the target (∼7 g/h) and a higher percentage of NP collection (> 72%) were observed, both for fluoride and the previously obtained CeO 2 oxide. The main physicochemical characteristics of NP were studied: structure, porosity, thermal stability and magnetic properties. It was found that the produced NP contains two crystalline phases: hexagonal CeF 3 (95 wt%, coherent scattering regions (CSR) ≈ 8 nm) and [Ce-O-F] or [Ce-F]. The last phase is obtained only at a high temperature, which is characteristic for the used NP synthesis method. The magnetic susceptibility of CeF 3 nanoparticles (NPles) coincides with the susceptibility of micron particles, indicating the potential for using such NPles as a contrast agent for tomography. High specific surface area (SSA) (CeO 2 –270 m 2 /g, CeF 3 - 62 m 2 /g) and large pore volume (0.35–0.11 cm 3 /g) allow the use of NP as nanocontainers for drug delivery.
