“…For several decade, combination of phosphate and fluoride as host matrix of Nd 3+ active ion as well as Er 3+ has become popular due to the powerful support to produce infrared emission. The structural characteristic of Nd 3+ and Er 3+ ions in fluorophosphate glass has been reported with the combine composition of sodium oxide [11], lead oxide [12], sulfate glass [13].…”

Transparent fluorophosphate glass containing face center cubic LiF crystals doped with Nd3+/Er3+ were succesfully characterized by melt-quenching method. The sample composition following chemical formula (65-x)P2O5-20LiF-14CaF-1Nd2O3-xEr2O3 (x = 0.0; 0.5; 1.0; 1.5 and 2.0 mol%). The density parameter was calculated using Archimedes method in distilled water and this value used to calculating of molar volume. Several physical properties of Nd3+/Er3+ co-doped LFP glasses were calculated and correlated with structural properties. The X-ray diffraction (XRD) spectrum used to verify the glasses structure. The further structural characteristic was investigated using FTIR. Based on the investigation is discovered that the prepared co-doped glasses shows amorf and high transparency.

“…Furthermore, previously published results proved that the presence of modifier oxides has an important influence on the structural, thermal, and spectroscopic properties of low phonon glass systems containing rare‐earth ions 25–27 . Among metal oxides that are components of glasses emitting NIR luminescence, titanium(IV) oxide (TiO 2 ) deserves particular attention 28,29 . The addition of TiO 2 increases the linear and non‐linear refractive indices, increasing the radiative transition probabilities and improving the non‐linear optical properties 30 .…”

Near‐infrared luminescence of Pr3+ and Tm3+ ions in titanate‐geramanate glasses have been studied for laser and fiber amplifier applications. The effect of the molar ratio GeO2:TiO2 (from 5:1 to 1:5) on spectroscopic properties of glass systems was studied by absorption, luminescence measurements, and theoretical calculations using the Judd‐Ofelt theory. It was found that independently of the TiO2 concentration, intense near‐infrared emissions at 1.5 μm and 1.8 μm were observed for glasses doped with Pr3+ and Tm3+ ions, respectively. Moreover, several spectroscopic and near‐infrared (NIR) laser parameters for Pr3+ and Tm3+ ions, such as emission bandwidth, stimulated emission cross‐section, quantum efficiency, gain bandwidth, and figure of merit, were determined. The results were discussed in detail and compared to the different laser glasses. Systematic investigations indicate that Pr3+‐doped system with GeO2:TiO2 = 2:1 and Tm3+‐doped glass with GeO2:TiO2 = 1:2 present profit laser parameters and could be successfully applied to near‐infrared laser and broadband optical amplifiers.This article is protected by copyright.

“…Within the family of germanate glasses, GeO 2 -PbO glass doped with RE 3+ ions has shown promising spectroscopic properties, supported by the relatively low phonon energy, large optical transparency in the visible and infrared regions, good thermal stability, excellent RE 3+ ions solubility, and a high refractive index. − Er 3+ doping has been extensively investigated for the development of amplifiers used for telecommunication devices operating at 1530 nm, corresponding to 4 I 13/2 → 4 I 15/2 transition. However, the small optical absorption cross section and its only three energy levels diagram do not favor the optimization of its performance for optical amplification. − Codoping Er 3+ with sensitizing ions such as Yb 3+ has been proven to be effective in solving the drawbacks.…”

In this work, germanate glasses of composition 59GeO2-41PbO in mol% doped with Er3+ ions were synthesized using the melt-quenching route. Au and Ag nanoparticles and Au@Ag bimetallic nanoparticles were formed on the surface of the germanate glasses by ion implantation followed by thermal treatments. X-ray diffraction patterns confirmed the amorphous structure of the implanted glasses. Molecular dynamics was used to simulate the GeO2–PbO glass structure. Surface plasmon resonance bands centered at 486, 537, and 574 nm, obtained through ultraviolet–visible absorption spectra, supported the formation of Ag, Au, and Au@Ag nanoparticles, respectively. Transmission electron microscopy (TEM) revealed the presence of spherical Au and Ag nanoparticles as well as the presence of nonspherical Au@Ag bimetallic nanoalloys. Refractive index n and extinction coefficient k were measured by ellipsometry. Judd–Ofelt theory was applied to evaluate the phenomenological intensity parameters Ωλ (λ = 2,4,6) , radiative parameters, and stimulated emission cross-sections for glasses doped with Er3+ and implanted with Au @Ag bimetallic nanoalloys. Efficient boosting of the near-infrared emission for the 4I13/2 → 4I15/2 transition was observed in the glass doped with Er3+ ions due to the presence of Au@Ag bimetallic nanoalloys. The possible cause of this improvement in luminescent intensity was attributed to the strong local field effect due to the efficient synergy between Au@Ag bimetallic nanoalloys and the Er3+ ions. The results obtained in this work indicate that the vitreous system GeO2–PbO glass doped with Er3+ ions and with the incorporation of Au@Ag bimetallic nanoalloys via ionic implantation exhibit excellent spectroscopic properties compared to other vitreous host glasses doped with the Er3+, indicating its potential applications in optical amplifiers.
