Luminescence properties of LaPO4-Eu nanoparticles synthesized in the presence of surface active oligoperoxide as template

► LaPO4-Eu nanoparticles were obtained in micelle-like structures. ► The nanoparticles reveal the different lattice symmetry depending on the size. ► The position of charge transfer band is sensitive to nanoparticle size. ► The surface defects of nanoparticles influence on Eu3+ luminescence decay kinetics.
