“…Detailed investigations on the influence of glass composition on the absorption and luminescence of doped rare-earth ions are very rare. In previous studies, a strong influence of the network modifier ions on the peak splitting of absorption peaks (Er 3+ in this case) [16] and luminescence emission peaks (Tb 3+ in this case) [15] and both in the case of Yb 3+ [17] was reported. A stronger peak splitting was found for glasses with higher NMO/Al 2 O 3 ratios and glasses with NM ions of lower field strength.…”

“…This has been shown for Yb 3+ doped aluminosilicate glasses as compared to phosphate or fluoride phosphate glasses and even to monocrystalline CaF 2 [9]. Recently, a number of systematic studies on the compositional effects on the optical properties of Sm 3+ [10][11][12], Eu 3+ [12,13], Dy 3+ [14], Tb 3+ [15], Er 3+ [16], and Yb 3+ [9,17] doped aluminosilicate glasses were reported. It has been shown that in addition to the OH concentration, the base glass composition also has a great influence on the optical properties, such as luminescence lifetime and spectral shape of absorption and emission.…”

Understanding the atomic structure of glasses is critical for developing new generations of materials with important technical applications. In particular, the local environment of rare-earth ions and their distribution and clustering is of great relevance for applications of rare earth-containing glasses in photonic devices. In this work, the structure of Gd2O3 doped lithium and potassium aluminosilicate glasses is investigated as a function of their network modifier oxide (NMO–Li2O, K2O) to aluminum oxide ratio using molecular dynamics simulations. The applied simulation procedure yields a set of configurations, the so-called inherent structures, of the liquid state slightly above the glass transition temperature. The generation of a large set of inherent structures allows a statistical sampling of the medium-range order of the Gd3+ ions with less computational effort compared to other simulation methods. The resulting medium-range atomic structures of network former and modifier ions are in good agreement with experimental results and simulations of similar glasses. It was found that increasing NMO/Al ratio increases the network modifier coordination number with non-bridging oxygen sites and reduces the overall stability of the network structure. The fraction of non-bridging oxygen sites in the vicinity of Gd3+ ions increases considerably with decreasing field strength and increasing concentration of the network modifier ions. These correlations could be confirmed even if the simulation results of alkaline earth aluminosilicate glasses are added to the analysis. In addition, the structure predictions generally indicate a low driving force for the clustering of Gd3+. Here, network modifier ions of large ionic radii reduce the probability of Gd–O–Gd contacts.

“…The second usually also results in a more subdivided peak structure, i.e., additional and more pronounced subpeaks become visible, which is not the case for the glass samples investigated here. However, it can nicely be observed for Er 3+ [ 2 , 31 ] and Tb 3+ [ 6 ] doped glasses of similar compositions. In our previous publications [ 2 , 5 ], we could clearly correlate the increased peak splitting to an increased coordination of the rare earth ions with non-bridging oxygen (NBO), which have a strongly localized negative charge and therefore expose the neighboring rare earth ion to a stronger electrical field than neighboring bridging oxygen atoms would do.…”

The Effect of Glass Structure on the Luminescence Spectra of Sm3+-Doped Aluminosilicate Glasses

et al. 2023

Peralkaline Sm3+-doped aluminosilicate glasses with different network modifier ions (Mg2+, Ca2+, Sr2+, Ba2+, Zn2+) were investigated to clarify the effect of glass composition and glass structure on the optical properties of the doped Sm3+ ions. For this purpose, the Sm3+ luminescence emission spectra were correlated with the molecular structure of the glasses derived by molecular dynamics (MD) simulations. The different network modifier ions have a clear and systematic effect on the peak area ratio of the Sm3+ emission peaks which correlates with the average rare earth site symmetry in the glasses. The highest site symmetry is found for the calcium aluminosilicate glass. Glasses with network modifier ions of lower and higher ionic radii show a notably lower average site symmetry. The symmetry could be correlated to the rare earth coordination number with oxygen atoms derived by MD simulations. A coordination number of 6 seems to offer the highest average site symmetry. Higher rare earth coordination probabilities with non-bridging oxygen result in an increased splitting of the emission peaks and a notable broadening of the peaks. The zinc containing glass seems to play a special role. The Zn2+ ions notably modify the glass structure and especially the rare earth coordination in comparison to the other network modifier ions in the other investigated glasses. The knowledge on how glass structure affects the optical properties of doped rare earth ions can be used to tailor the rare earth absorption and emission spectra for specific applications.

“…Similarly, the optical waveguides based on erbium-doped glass, which can realize the miniaturization of integrated optical devices, also play an important role in the field of all-optical communication. aluminosilicate glass substrate, due to its excellent optical properties, such as high damage threshold, high transmittance in the near-infrared band, and so on, , has gradually attracted the attention of researchers and become a new potential alternative gain substrate glass.

The symmetrical optical waveguide structures are fabricated in Er 3+ -doped aluminosilicate glass using 800 nm femtosecond laser writing in kHz repetition frequency regime. The impact of writing parameters on the waveguide preparation with a 10× microscope objective in the longitudinal writing scheme was studied in detail. The experimental results show that, under a fixed pulse energy value of 20 μJ, the waveguides can be realized with the scan speed from 20 to 160 μm/s, and with a fixed scan speed value of 160 μm/s, the waveguide can be prepared under an inscription energy range of 5−30 μJ, indicating that the waveguide can be realized in a wide range of writing parameters. The near-field mode intensity image shows that the waveguide region possesses excellent light guiding properties. Based on the refractive index profile reconstruction method, the maximum refractive index increase in the waveguide region is estimated to be about 5.5 × 10 −4 . The lowest propagation loss of the waveguide was measured to be about 1.51 dB/cm by the waveguide side scattering method. The microfluorescence spectra show that the gain characteristics of the waveguide region are well maintained after laser processing. This work shows that the fabrication of embedded optical waveguides using ultrashort pulse laser in Er 3+ -doped aluminosilicate glass has strong feasibility and great potential to create active gain devices in the field of integrated photonics and all-optical communication.
