The effect of the hydrothermal treatment temperature of a colloidal solution of LaF3 nanoparticles in an autoclave (60–140 ◦C) on the particle size, the size of the coherent scattering region, and the concentration of paramagnetic centers has been studied. The samples were characterized using X-ray diffraction, transmission electron microscopy and magnetic resonance methods. The optimal hydrothermal treatment temperature has been determined to obtain particles with the largest size, best crystallinity, and minimum paramagnetic center content for practical applications. Theoretical estimates of the 19F nuclear magnetic relaxation times for synthesized LaF3 samples are presented, which are in good agreement with experimental data. The work may be useful in understanding the effect of hydrothermal treatment on the structure and magnetic interactions in nanoscale fluorides.
