Abstrakt:	The series of LaF3 nanoparticles with closed pores filled with water H2O and heavy water D2O are synthesized by the hydrothermal treatment in autoclave at 140 °C, 160 °C, and 180 °C for 24 h. The samples are characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and nuclear magnetic resonance (NMR) cryoporometry techniques. According to particle size distribution, the mean diameter of synthesized particles ranges from 31 to 45 nm. The pore sizes for H2O and D2O inside nanoparticles are determined by NMR cryoporometry and TEM methods. The method for the synthesis of nanoparticles with closed pores filled with heavy water is proposed. [ABSTRACT FROM AUTHOR]
