“…Also, our experimental results are well confirmed by the phenomenological intensity parameters calculated from the Judd–Ofelt theory 44, 45. In particular, the Ω 2 intensity parameter is a convenient tool in order to establish differences in the covalency degree of the Dy 3+ and its surroundings 46–48. The lower value of the Ω 2 parameter indicates the higher degree of symmetry around the rare‐earth ion and weaker covalency between the rare earth and its surrounding ligands.…”

ARTICLE INFO ABSTRACT The transition metal ions such as Copper, Silver and Titanium when dissolved in B 2 O 3 glass matrix, even in very small quantities, influence the properties very strongly. In the present study Borate Glasses doped with different transition metals have been prepared in laboratory by using Melt Quench Technique. The absorption spectra of the prepared samples have been obtained by using UV/Visible spectroscopy. The Band-Gap Energy (E g) values are obtained by using Tau's Plots. The significant increase in E g values from 2.60 to 3.18 eV is observed. A transmission window is observed in the spectra of Cu-doped glass sample which indicates the possibility of large number of applications in the field of nonlinear optics. An increase in the density values from 4.851 to 5.038 gm/cm 3 is observed with the addition of TMOs having higher atomic number.

“…The development of rare earth (RE 3+ ) ions doped glasses with good thermal, mechanical and chemical durability are highly essential for the design of high performance lasers, optical amplifiers and white light emitting diodes (LEDs) [1, 2, 3, 4, 5, 6]. Different multi-component borate glasses have been considered for technological applications in many areas and among them, the lithium zinc borosilicate (LZBS) glasses have attracted the researchers for the development of visible lasers and amplifiers due to their good optical transmission, low phonon energy, low glass transition temperature, high refractive index, high dielectric constant and high thermal expansion coefficient [7, 8, 9, 10].…”

Different concentrations of Dy3+ ions doped lithium zinc borosilicate glasses of chemical composition (30-x) B2O3 - 25 SiO2 -10 Al2O3 -30 LiF - 5 ZnO - x Dy2O3 (x = 0, 0.1, 0.5, 1.0 and 2.0 mol%) were prepared by the melt quenching technique. The prepared glasses were investigated through X-ray diffraction, optical absorption, photoluminescence and decay measurements. Intensities of absorption bands expressed in terms of oscillator strengths (f) were used to determine the Judd-Ofelt (J-O) intensity parameters Ωλ (λ = 2, 4 and 6). The evaluated J-O parameters were used to determine the radiative parameters such as transition probabilities (AR), total transition probability rate (AT), radiative lifetime (τR) and branching ratios (βR) for the excited 4F9/2 level of Dy3+ ions. The chromaticity coordinates determined from the emission spectra were found to be located in the white light region of CIE chromaticity diagram.
