Abstract:

Luminescence vacuum ultraviolet time-resolved spectroscopy is used to study electronic excitations and energy transfer in Ce3+-doped crystals of gadolinium and yttrium oxyorthosilicates excited by synchrotron radiation in the vacuum ultraviolet (4-30 eV) and x-ray (50-200 eV) regions. At T = 10 K, both crystals exhibit intrinsic electronic excitations whose radiative relaxation occurs through fast (tau = 3 ns) and slow (microsecond) channels, which correspond to two possible types of self-trapped excitons. A comparison of the relaxation of above-edge and core electronic excitations in the Ce3+-doped crystals of gadolinium oxyorthosilicate and lanthanum beryllate indicates that the nature of the charge carriers involved in the recombination processes of energy transfer to luminescence centers is diverse.
