摘要	The fluorescence intensity of divalent samarium (Sm2+) ions doped in alkaline-earth fluorohalides were found to decrease under the optical excitation from a blue laser, a green laser or even a red laser. This photobleaching effect has a mysterious and unknown mechanism. After the bleaching effect happened, no Sm3+ ions generation, no relative spectral change in Sm2+ emissions and no lifetime decrease for the levels of Sm2+ ions could be observed. Under blue or green-laser irradiation, the decrease of Sm2+ fluorescence showed a perfect biexponential function; however, when the exciting photon energy was lower than that of D-5(0) -> 7F(0) transition, the photobleaching effect could not be observed anymore. An identical mechanism in the photobleaching with that in the spectral hole burning was proposed. (c) 2004 Elsevier B.V. All rights reserved.
