Peculiarities of luminescence decay of Ce:LaF3 nanoparticles depending on conditions of hydrothermal treatment

Abstract

Luminescence decay properties of crystalline LaF3 nanoparticles containing 12 % of Ce3+ ions collected at different stages of microwave hydrothermal treatment were studied. The microwave treatment has led to improvement of surface perturbed sites luminescence together with reducing PL decay time of regular sites apparently due to higher surface/volume ratio.
