Abstract

Lanthanum fluoride nanoparticles doped with Nd³⁺ ions obtained via solvothermal method have been presented. Doped nanoparticles were prepared in two-step method. Firstly rare-earth chlorides were synthesized from oxides and then they were used to prepare LaF₃ particles. The luminescence spectra shows typical for crystalline materials Stark splitting at 880 nm corresponding ⁴F_3/2 to ₄I_9/2 level transition and 1060 nm matching ⁴F_3/2 to ⁴I_11/2 level transition. The highest luminescence intensity was achieved for sample doped with 0.75% wt. of Nd³⁺, and the longest decay time for sample doped with 0.5% wt. which reached 328 μs. The XRD pattern analysis confirmed that obtained material consists of crystalline LaF₃, the grain size was estimated from Sherrer's formula and equaled about 25nm.
