摘要	Optical absorption, fluorescence, excitation and time-resolved spectra, and fluorescence dynamics were studied in Eu2+- and Eu3+-codoped aluminosilicate glasses. The results indicated that the energy transfer occurred between Eu2+ and Eu3+ ions, in which the energy corresponding to the 4f(6)5d to S-8(7/2) transition of Eu2+ ions caused excitation of the Eu3+ ions to the D-5(J) level. Some of the electrons in the ground state F-7(0) were thermally excited into the F-7(1) state at room temperature, and thermal populations of the F-7(1) level had great effects on the spectral shape of the D-5(0)-F-7(2) emission. The effect of light irradiation at different wavelengths on fluorescence was systemically studied. The visible, ultraviolet and x-ray irradiation caused a decrease in the fluorescence of Eu2+ and/or Eu3+ ions. Frequency selective excitation experiments were performed at 10 K and room temperature. Instead of forming a spectral hole, the intensity of the F-7(0)-D-5(0) transition decreased as a whole. This was attributed to the interaction of Eu3+ ions with the two-level systems existing in the glass network. (C) 2002 American Institute of Physics.
