Luminescent properties in visible spectral range of crystalline LaF3 nanoparticles containing 1 % and 5 % of Sm3+ ions before and after microwave hydrothermal treatment and also Sm:LaF3@LaF3 core-shell nanoparticles were studied. The LaF3 surface layer resulted in lowering the luminescence decay time apparently due to eliminating surface quenching factors. This opens the way to manage luminescence and energy transfer properties of the material.
