Diffusion of 5p-holes in BaF2 nanoparticles
Source abstract
Abstract
Abstract The kinetic parameters of core-valence luminescence for BaF2 nanoparticles with different sizes were studied under synchrotron radiation excitation with photon energy of 18.8 eV at room temperature. In contrast to BaF2 single crystals the decay kinetics of nanoparticles is shown to be non-exponential indicating the luminescence quenching. We assume that the quenching of core-valence luminescence is caused by the diffusion of core holes to nanoparticle surface. The diffusion length of the core holes in BaF2 has been estimated as 2–3 nm using diffusion model of luminescence quenching in nanoparticles.
