N2 - Samarium doped bismuth borate glasses with composition 66.7Bi2O3: (33.3-x)B2O3: x Sm2O3 (where x = 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) have been prepared by melt quenching technique. The physical, optical, photoluminescence and X-rays luminescence properties were investigated. The densities and molar volumes were not found the relationship with the increasing samarium concentration. The photoluminescence emission spectra shows broad emission bands due to 4G5/2→6HJ (J=5/2, 7/2, 9/2, 11/2) transitions when excited with 473 nm. The decay curves of 4G5/2 level exhibited single exponential behavior for all the concentrations and the measured lifetimes are found to depend strongly on samarium concentrations. The X-rays emission spectra were measured at the X-rays of intensity 100kV and current 1.5mA. The emission peaks observed at 569, 598, 641 and 705 nm. And the intensity of luminescence increase as samarium concentration increase.
