Two-Colour Excitation of Impurity Trapped Excitons in Wide Bandgap Insulators
Impurity trapped excitons (ITEs) occurring in divalent ytterbium doped calcium and strontium fluoride crystals have been investigated by exploiting the radically different radiative decay rates of the lowest exciton state and higher excited states, utilizing a novel two-colour transient photolumines...
