glasses (where x = 0.05; 0.1; 0.5; 1.0;
2.0 and 4.0 mol%). The glasses have been prepared using
the melt-quenching method with total mass of 20 grams
mixed in alumina crucible. The optimum size of 3 mm x 10
mmx 10 mm glasses were obtained by cutting and polishing
for absorption, infrared, photoluminescence and excitation
spectra investigations. Density, XRD and also energy band gap
properties were observed to explain the physical phenomena
of the glass samples. The results show that the glass
structure of Sm

doped borate glass system confirms to the
amorphous phase. The addition of Sm

increases. The different pattern occur on photoluminescence
