Abstract
Reduction effects on the optical properties of Sm2+ ions doped in SrB4O7 and SrB6O10 crystals were studied by measurements of luminescence intensity decay as a function of time, X-ray irradiation and laser power effects on the photoluminescence. The fluorescence intensity of Sm2+ doped in SrB4O7 and SrB6O10 crystals decreased upon excitation at 488 nm of Ar+ laser and this so-called photo-bleaching effect was highly dependent on the sample preparation conditions. The fluorescence intensity of Sm2+ doped in SrB4O7 decreased about 13%, while it decreased about 55% in the SrB6O10 crystal irradiated with X-ray for 10 h. Differences of photo-beaching effect and other optical properties of Sm2+ doped in SrB4O7 and SrB6O10 are discussed.
