“…A small deviation in wavenumber with chemical composition has been seen because of an increment in the [BO 4 ] units in the glass network [35,36]. The peak at 910 cm −1 is recognized as the fundamental peak promising due to induced stretching vibrations in B−O bonds of [BO 4 ] from diborate groups [4,30]. The peak prominent at around 1190 cm −1 can be intuited to asymmetric stretching induced vibrations due to B−O bonds of [BO 4 ] units from pyro and ortho borate groups [4].…”

The absorption peaks in the range of 1200-1600 cm −1 are ascribed to B−O the stretching induced vibrations which are developing in the [BO 3 ] units from the boroxol rings.…”

“…These transparent materials have received ample attention in the fields of science and technology [1]. For as far back as decade, many researchers have explored bismuth-contained glasses due to their remarkable advantages in the field of photonics and their application in optical isolators, infrared transmission components, optoelectronics, optical fiber amplifiers, laser 2 of 17 systems, ultrafast switches, and various photonic devices [2][3][4][5]. When borate is added to the bismuth glass network, it leads to larger optical basicity, a high refractive index, longer IR (infrared) cut-off, and second and third order non-linear optical susceptibility.…”

Bismuth based quaternary glasses with compositions BiBLM: 50Bi2O3–20B2O3–15Li2O–15MO (where MO = ZnO, CdO, BaO, and PbO) were processed by conventional melt quenching. The effectiveness of various modifier oxides on the optical and structural properties of the developed glasses was studied systematically by XRD, DSC, FTIR, Raman, and optical absorption (OA) measurements. The synthesized glass specimens were characterized by XRD and the patterns demonstrated an amorphous nature. The physical characteristics such as molar mass, density, and OPD values were found to increase with an increase in the molar mass of the modifier oxides, while there was a decrement in oxygen molar volume, thus resulting in decrement of complete molar volume of the prepared glasses. From DSC analysis, incorrigible reduction and enhancement of Tg and thermal stability among various modifier oxides in the glass network was noticed. Optical absorption data for glass specimens have confirmed the decrease in both direct and indirect optical band gap values among various modifier oxides incorporation. These investigations support the obtained Urbach energy (UE) and metallization criteria of synthesized glasses. The ionic characteristic for the glass specimens were confirmed by the values of electronic polarizability and electronegativity. The Raman and FT-IR spectra of the glass specimens displayed the existence of BiO3, BiO6, ZnO4, CdO4, BaO4, BO3, PbO4, and BO4 structural units within the glass matrix. These structural results can support the applications of as-developed glasses in the area of photonics.

“…The characteristics of 4f N -4f N electron transitions are long lifetimes, sharp absorption lines and excellent coherence properties, and 4f N -4f N-1 5d electron transitions are broad absorption bands and shorter life times [3]. The 4f N -4f N electron transitions emit luminescence from the ultraviolet (UV) to the infrared region due to shielding effects of the outer 5s and 5p orbital on the 4f electrons [4]. In glass materials, neodymium oxide has been used for several purposes.…”

In this work, properties of Nd3+ in Gd2O3-CaO-SiO2-B2O3 glass systems with composition 25Gd2O3-10CaO-10SiO2-(55-x)B2O3-xNd2O3 where x = 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol% were investigated. The optical absorption spectra show peaks at 4F3/2 (877 nm) , 4F5/2+2H9/2 (802 nm), 4F7/2+4S3/2 (743 nm), 4F9/2 (682 nm), 2H11/2 (627 nm), 2G7/2 +4G5/2 (582 nm), 4G7/2 +2K13/2 (527 nm), 4G11/2 (481 nm), 2P1/2 (427 nm) and 2L15/2 + 4D1/2 + 1I11/2+ 4D5/2+ 4D3/2 (355 nm) reflecting the Nd3+ ions in glass matrices. The densities were increased with increasing of Nd2O3 concentration. This indicates the increase of the molecular weight by the replacement of B2O3 with a heavier Nd2O3 oxide in the glass. The upconversion luminescence spectra show bands at 393 nm for all Nd2O3 concentration and the strongest intensity from 2.5 % mol of Nd2O3 was obtained. For NIR luminescence, the intensity of Nd3+ emission spectra increases with increasing concentrations of Nd3+ up to 1.5 mol% and beyond 1.5 mol% the concentration quenching is observed.

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 to4G5/2→6HJ(J=5/2, 7/2, 9/2, 11/2) transitions when excited with 473 nm. The decay curves of4G5/2level 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.
