A series of quaternary tellurite‐based glasses (72−x)TeO2 + 25B2O3 + 3K2CO3 + xDy2O3, where (x = 0, 0.5, 1, 1.5, 2, 2.5), are prepared using melt quenching technique. The effect of dopants on structural, physical, optical, and thermal properties of alkali boro‐tellurite glasses are studied using the differential thermal analysis (DTA) technique, UV–vis spectrometer, and photoluminescence technique. The density of as‐prepared samples has been obtained using the conventional Archimedes principle and other physical parameters, viz. molar volume and ion concentration, are also calculated using density. The optical absorption spectra exhibits different excited states of Dy3+ corresponding to 6H15/2→ 6F5/2(∼805 nm), 6F3/2(∼755 nm), 4F9/2 (∼473 nm), 4I15/2 (∼454 nm), 4G11/2 (∼427 nm), 4F7/2(389 nm), 4P3/2(∼366 nm). With the increase in Dy+3 concentration, an increase in optical bandgap, density, and molar volume as well as decrease in molar reflectivity, and reflection loss is evident from this study. The effect of Dy+3 ion concentration on Y/B intensity ratios and CIE chromaticity coordinates have been evaluated to understand the possible applications of aforementioned glass samples for white‐light‐emitting diodes (WLEDs). Moreover, various shielding parameters, viz. half value layer (HVL), mean free path (MFP), effective atomic number (Z eff), mass attenuation coefficient (MAC) have also been determined to understand the shielding characteristics of as‐prepared glass samples.

“…Calculation of polaron radius shows that decrease from the range of 1.73 Å to 1.09 Å. The polaron radius and ionic radius, which decrease with increasing of Nd2O3, lead to a decrease of the Nd-O bond length so the Nd-O bond strength increases and produces a greater field strength (Aljewaw et al, 2020). The significant increase in field strength from 1.626 -4.065 (×10 15 cm -2 ) is due to stronger bond between Nd 3+ ions and B ions (Wu et al, 2014).…”

The Nd2O3 doped lead borate glass with composition 45B2O3-(40-x)PbO-11ZnO-4Na2O-xNd2O3 (x=0; 0.5; 1.0; 1.5; 2.0; 2.5) mol% were fabricated using melt quenching method at 950oC for 35 minutes. The characterization of physical properties of glasses doped Nd2O3 were measured by density (ρ) based on the Archimedes principle. The other physical parameters such as molar volume (Vm), oxygen packing density (OPD), polaron radius (rp), ionic radius (ri), field strength (F), molar refraction (Rm), and metallization (Mn) were calculated using equation which derived from density. According to the measurement, the density of glasses decreased from 5.774 to 4.527 gr/cm3 while molar volume oppositely increased from 23.17 to 30.18 cm3/mol due to atomic mass of Nd (144.24) smaller than Pb (207.2). Along with the increase of molar volume, there were decreasing of the OPD, the polar radius (1.731 －1.095) Å and the ion radius (4.296－2.717) Å iof glasses Meanwhile, the field strength and metallization properties of the glasses increased as a result of the reduction rp and ri. The investigation of molar refractive shows an increasing trend because the addition of the concentration Nd2O3.

In this study, a series of barium-boro-tellurite glass hosts with varying concentration of Dy2O3 doping (0 to 1.25 mol%) were made by melt-quenching method. A study was conducted to investigate how Dy2O3 dopants affect the physical and spectroscopic traits of glasses. Raw materials including barium oxide (BaO), tellurium dioxide (TeO2), boron oxide (B2O3), and dysprosium oxide (Dy2O3) were used to produce these glasses. XRD patterns of the samples showed a broad hump and absence of long-range periodic lattice arrangements, indicating their amorphous nature. The Raman spectral analyses displayed the various vibration modes where the most intense band caused by BaO vibrations at 300 cm-1 and 450 cm-1 corresponding to the symmetric stretching vibration mode of Te–O–Te intra-chain bridges. The peak at 750 cm-1 was due to TeO4 and Te-O-Te vibration modes. The value of optical band gap energy was decreased from 3.155 to 2.1894 eV and then increase at higher Dy2O3 level (0.75 to 1.25 mol%). At Dy3+ contents between 0.25 to 1.25 mol% seven absorption bands were observed at 390, 424, 452, 750, 797, 895 and 1092 nm due to the electronic transitions in Dy3+. The glass refractive indices were raised from 2.3563 to 2.6584 and then decreased at higher Dy2O3 contents which was mainly because of the generation of more bridging oxygen (BO) in the glass matrix. The value of glass electronic polarizability and oxide ions polarizability calculated using LorentzLorenz equation showed a decrease with the rise of Dy2O3 contents, which was ascribed to the presence of fewer non-bridging oxygen (NBO). The optical basicity of the proposed glass hosts was calculated using Duffy and Ingram equation which was decreased with the increase of doping contents. In addition, the optical transmission was increased and reflection loss was reduced with increasing Dy+3 levels. The value of metallization parameter below 1 proved the true amorphous nature of the prepared samples. All the glasses revealed blue and yellow photoluminescence emission peaks due to 4F9/2→ 6H15/2, and 4F9/2 →6H13/2 transitions in Dy3+, respectively. The proposed glass compositions may be beneficial for the advancement of solid-state lasers.
