Evolution of glass structure during femtosecond laser assisted crystallization of LaBGeO5 in glass
Source abstract
Abstract
Abstract Single crystal LaBGeO5 architecture formed in La2O3-B2O3-2GeO2 glass serves as a model system for understanding of the transformation from glass to single crystal under fs laser irradiation. This transformation is highly sensitive to glass composition, raising the need to understand how the glass structure and composition evolve during crystallization. In this work, micro X-ray absorption spectroscopy and X-ray fluorescence mapping were used to study the glass structure and composition preceding LaBGeO5 crystallization in the region surrounding the single crystal growth front. The results show precipitation of germanium nanoparticles, as well as anisotropic segregation of Ge and La prior to LaBGeO5 crystallization, which are explained assuming electromigration in high fields within the plasma formed by the fs laser irradiation. However, these nanoparticles do not serve as sites for heterogeneous nucleation. The similarity of local structure around Ge in the starting glass and the ultimate crystal appears to enhance the crystallization process.
