Quantitative calculation and prediction of the optical and spectroscopic properties of Er 3+ -doped tellurite glass

One of the challenges in glass science is the prediction and calculation of glass performance theoretically to avoid experimental trials and errors, particularly for laser glasses that need to be designed with certain mechanical, optical, and spectroscopic characteristics. In this work, the physical and luminescent properties of new Er3+-doped BaO-Ga2O3-TeO2 (BGT) glasses were quantitatively predicted and determined via the phase diagram approach. A few representative glass components were selected to experimentally verify the prediction results and analyze the source of errors. The determined physical and luminescent properties are in good agreement with the experimental results, with errors less than 2% and 10%, respectively. Using these results, a database of glass properties was established, and the property data of glass components in the glass-forming region were provided. The results show that the phase diagram approach allows the quantitative prediction and determination of the physical and luminescent properties of Er3+-doped BGT glass. Thus, it is a new approach for enhancing the basic database of glass and reducing the research cost for developing new laser glass materials.
