Quantitative prediction of the structure and luminescence properties of Nd³⁺ doped borate laser glasses

Abstract

Although great advance has been made in glass science, predicting luminescence properties of laser glass poses a significant challenge for scientists due to the complex relationship between the composition, structure, and properties of the rare earth ions doped laser glasses. The development of high‐performance laser glass usually relies on intuition and trial‐and‐error. Recently, with the proposal of the materials genome engineering, the “glass genome” has also attracted much attention. Here, the structure of the Nd3+ doped B2O3‐Li2O laser glasses was analyzed using Fourier transform infrared spectra and nuclear magnetic resonance, revealing that the glass contains similar glass‐forming ion‐centered coordination polyhedron structure groups to the neighbor congruent glassy compounds. The structure and properties of glass largely depend on the neighbor congruent glassy compounds. Therefore, the structure and luminescence properties of Nd3+ doped B2O3‐Li2O and B2O3‐MgO‐Li2O laser glasses can be quantitatively predicted via the neighbor congruent glassy compounds. The predictive values are in good agreement with the experimental data, which indicates that our approach is an effective way to predict the structure and luminescence properties of Nd3+ doped borate laser glasses.

Quantitatively predicting the optical and spectroscopic properties of Nd3+‐doped laser glasses

“…This method is based on the basic theory of glass formation and avoids complex calculation coefficients in traditional additive methods. Previous works in our laboratory also proved that the structure and properties of laser glasses can be accurately predicted to a certain extent through this method 19–23 …”

“…Previous works in our laboratory also proved that the structure and properties of laser glasses can be accurately predicted to a certain extent through this method. [19][20][21][22][23] In this study, we aim to further study the adaptability and accuracy of this method for traditional laser glasses, such as silicate, phosphate, and borate glasses, particularly for the prediction of their spectroscopic properties. All these glass systems are derived from main components of commercial laser glasses commonly used in 1 μm solid laser and fiber laser.…”

The multicomponent oxide glass as a statistical ensemble of neighboring glassy compounds in the composition space

“…These approaches have successfully decoded the “glass genome” at different scales. Previously, we demonstrated that the glass‐forming ion‐centered coordination polyhedron of the resulting glass is similar to the coordination polyhedron of the neighboring glassy congruent compounds of the glass, which can be considered as the “glass genes.” 21,22 Moreover, the structure and luminescence properties of multicomponent oxide laser glasses have been quantitatively predicted based on the “glass genes.” 1,21,22 Nevertheless, this method lacks physical interpretation. In addition, this method is not suitable for all multicomponent oxide glass systems because some neighboring glassy congruent compounds of multicomponent oxide glass may not be possibly prepared by using the conventional melt‐quenching.…”
