| Abstract | ||||
| The rare-earth-doped glasses have a great significance for promise applications in optical devices and laser technology. The glass samples prepared by melt quenching technique. XRD, FTIR, UV/VIS/NIR spectrophotometer and photoluminesces used to study the structure and properties of the glass samples. And found that the glass samples in the amorphous, the lead oxide enters the glass network as a former, analysis of splitting of Nd3+ in glasses, UV—Vis—IR spectra exhibit ten prominent bands centered at 428, 457, 471, 511, 524, 582, 624, 679, 744, 803 and 875 nm correspond to the transition from the ground state 4I9/2 to 2P1/2, 4G11/2, 2D3/2+2G9/2+2P3/2, 4G9/2, 2K13/2+4G7/2, 4G5/2+2G7/2, 2H11/2, 4F9/2, 4S3/2+4F7/2, 4F5/2+2H9/2, and 4F3/2 respectively. The Judd–Ofelt intensity parameters Ωλ (λ=2, 4, 6) determined from the absorption bands intensities of as Ω6>Ω4>Ω2. The emission peak intensity at 625 nm decreases with the Nd3+ concentrations increase due to the quenching effect. | ||||
