Thermal and fluorescence properties of Nd2O3-doped Gd2O3-Ga2O3-GeO2 glass based on the Judd-Ofelt theory

Dy3+‐ and/or Sm3+‐doped glass–ceramics containing NaGd(MoO4)2 crystalline phase for warm white light applications

“…From another aspect, the strong aggregation of Dy 3+ ions makes the glass network structure denser, and thus, the density increases with increasing Dy 2 O 3 doping. [48][49][50] Moreover, as the amount of Dy 2 O 3 increases, the molar volume of the precursor glass increases. According to the formula for molar volume, it can be seen that the variation of V m is related to the variation of molecular weight in addition to being affected by density.…”

Structural, photoluminescence, and optical characteristics of a Sm3+‐doped lead borate–strontium–tungsten glass system: Evaluation of Judd–Ofelt intensity parameters and radiative properties

“…Amongst several glass‐forming oxides [1–4], boric acid (B 2 O 3 ) is the most abundantly used due to its small B 3+ ion size and strong covalent B–O bond strength. Borate‐based glass are considered to have the highest glass formation tendency [5].…”

Spectroscopic and Judd-Ofelt Analysis of Nd3+ Ion Doped Lithium Antimony-Borate Glasses for Visible and Near Infrared Laser Application Compared to Standard Emission at 1.06 μm

“…[1][2][3][4][5][6][7][8][9] These materials took on the ultimate importance due to their attractive, functional properties, namely the possibility of generating high fluorescence intensity, a distributed lifetime from nano to milliseconds scale, and a good monochromatic aspect for a given transition. 10 The optimization of these properties requires the appropriate choice of the lanthanide including its concentration and its ligand, and thus the glassy matrix in which is incorporated. 2 The electronic transitions in the trivalent lanthanides are of the 4f-4 f or 4f-5d type are mainly forced electrical in nature; their intensities can be determined via the Judd-Ofelt model.…”

“…11,12 Magnetic transitions have a limited contribution and are governed by specific selection rules. 13 Trivalent lanthanides that can emit a wide range of spectrum in infrared and visible; 10,[14][15][16][17][18][19] and often the evaluation of a given color is done in the BGR (Blue, Green and Red) system in terms of chromatic coordinates and appropriate temperature. 20 Neodymium is renowned for its infrared luminescence, and it is applied in telecommunications.…”

“…20 Neodymium is renowned for its infrared luminescence, and it is applied in telecommunications. 10 Heavy metal oxide glasses (HMOGs), in particular based on antimonate, are promising with respect to lanthanide doping. They exhibit low phonon energy, high refractive index and third-order nonlinear susceptibility.…”
