Investigation of the spectral characteristics of Sm ions in lead borosilicate glass for photonic applications.

Different concentrations of Sm O -doped lead borosilicate glass were synthesized using a melt-quenching method and their characteristics were analyzed using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy absorption, emission, and decay curves. From the XRD patterns, the noncrystalline nature of titled glass was confirmed. The structural groups that existed in the host glass were observed from FTIR spectra.

Erbium(III) ion-doped borate-based glasses for 1.53 μm broad band applications.

Novel erbium(III) ion-doped borate-based glasses (Er :BCNF) by conventional melt-quenching technique were designed and synthesized. The glasses were characterized for their structural, vibrational and spectroscopic properties. The nephelauxetic ratio, bonding parameters, and Judd-Ofelt (JO) intensity parameters (Ω λ = 2, 4 and 6) were determined by using absorption spectrum of 1 mol% Er O doped glass.
