The effects induced by 3.50 eV and 4.66 eV laser photons on the blue luminescence, characteristic of silica nanoparticles, were investigated by monitoring its intensity during and after exposure. The luminescence trend is found to be dependent on the UV photon energy thus evidencing the conversion of luminescent defects towards stable and metastable states.

Abstract
The effects induced by 3.50 eV and 4.66 eV laser photons on the blue luminescence, characteristic of silica nanoparticles, were investigated by monitoring its intensity during and after exposure. The luminescence trend is found to be dependent on the UV photon energy thus evidencing the conversion of luminescent defects towards stable and metastable states.
