摘要:
Red luminescence (at wavelength about 622 nm) from Eu3+ ions embedded in PbO-Bi2O3-Ga2O3-BaO glass hosts is reported for room and liquid helium temperatures. The substantial influence of energy transfer processes between the host and Eu3+ ions is shown experimentally through the dependences of photoluminescence on light polarization and excitation wavelength. Only polarized, excited pulsed XeII laser light (lambda = 714 nm) gives substantial luminescence with efficiency up to 14.3%. The role of phonon-relaxation subsystem in the observed luminescence is discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.
