Zusammenfassung / Abstract

The present study aimed to methodically determine the nanophases formation within the Li2O-Al2O3-SiO2 glass-ceramics and subsequently their contribution to the optical properties.

The optical transmission spectroscopy has been used as the main method. This method has the advantage that the (internal)-transmission spectrum of a material refers to the absorption and scattering efficiency of species and phases within the material.

Furthermore, a Fit-tool with an interface to MATLAB software has been developed. Using the theory about the nucleation, the absorption and scattering, the tool enabled the determination of the nucleation kinetic as well as the contribution of individual species and phases to the optical properties of glass-ceramics.
