N2 - The LaF3 film formed by c-axis oriented uniform-size nanocrystals with diameter of about 400 nm was obtained on the surface of La(NO3)3 solution in 1 M HNO3 by interfacial reaction with HF in the gas medium. The effect of solution acidity on the layer morphology is reported. The film formed by LaF3:Eu3+ oriented nanocrystals with radial compositional gradient has been prepared in a similar way. The synthesized crystals were characterized by SEM, TEM, HRTEM, EPMA, TEM-EDX mapping, XRD analysis, Raman and luminescent spectroscopy. The LaF3:Eu3+ doped nanocrystals can potentially be used as luminescent material.
