Abstract:

We have investigated UV luminescence with a subnanosecond time resolution of Li6GdB3O9:Ce crystal fibers upon their ultrasoft X-ray selective excitation at 10 and 293 K in the range of 4d -> 4f core transitions. We have revealed an intense fast-decaying subnanosecond luminescence component, which is caused by a high local density of electronic excitation and Auger core hole relaxation processes, and modulation of the luminescence excitation spectrum by an absorption band of the 4d-4f photoionization giant resonance in the energy range 135-160 eV.
