文摘

The LaPO₄-Eu nanoparticles were synthesized by the template method using the surface active oligoperoxides. Size and morphology characteristics of the LaPO₄-Eu nanoparticles were studied using X-ray, TEM and luminescence spectroscopy analysis. The results of X-ray diffraction and luminescence data reveal the different (hexagonal or monoclinic) symmetry of the lattice for nanoparticles depending on the size (annealing temperature). The essential influence of near-surface layer on luminescence decay kinetics is revealed.
