Abstract:

This paper reports on luminescence studies of lithium borate Li6Gd(BO3)(3) doped with Eu3+ and Ce3+ and Li6Eu(BO3)(3) crystals upon selective excitation by synchronous radiation in the pump energy region 3.7-27 eV at temperatures of 10 and 290 K. The effective energy transfer between the rare-earth ions Gd3+ -> Ce3+ and Gd3+ -> Eu3+ is found to operate by the resonant mechanism, as well as through electron-hole recombination. A study is made of the fast decay kinetics of the Ce3+-center activator luminescence under intracenter photoexcitation and excitation in the interband transition region. The mechanisms underlying luminescence excitation and radiative relaxation of electron states of rare-earth ions are analyzed and energy transfer processes active in these crystals are discussed.
