In this work we report the visible and infrared emissions of the color centers created in bilayer LiF:KCl thin films, obtained by pumping them with appropriate Ar+ and Ti:Sapphire laser lines, The large concentration of color centers induced by low-energy electron irradiation in a thin dielectric layer of controlled depth allows to investigate the spectroscopic properties of point defects which cannot be found in mixed crystals.

Abstract
In this work we report the visible and infrared emissions of the color centers created in bilayer LiF:KCl thin films, obtained by pumping them with appropriate Ar+ and Ti:Sapphire laser lines, The large concentration of color centers induced by low-energy electron irradiation in a thin dielectric layer of controlled depth allows to investigate the spectroscopic properties of point defects which cannot be found in mixed crystals.File in questo prodotto:
