[Calculation of optical parameters and investigation of luminescence spectra in Sm3+ doped borate glasses].
In the present paper, Sm3+ doped borate glasses (LBLB) with high effective visible fluorescence emission have been synthesized. The absorption and fluorescence spectra of this glass were measured and analyzed. The absorption spectra were fitted by J-O theory, and the intensity parameters omega = (2, 4, 6) were found to be 6.81 x 10(-20), 4.43 x 10(-20), and 2.58 x 10(-20) cm2, respectively, then the relative intensity of spectral lines of every energy level transition, radiative transition probabilities, radiative lifetimes, and fluorescence branching ratio were calculated. Under the excitation of UV light, Sm3+ doped borate glasses (LBLB) emit bright salmon pink light. The excitation spectra indicate that argon laser is an effective excitation source in Sm3+ doped LBLB glasses.
