Abstract

This dissertation combines solid-state research and chemistry didactics. The solid-state part is about fundamental research in the field of high-pressure group 13 element borates. By means of a 1000 t press, two new gallium- and seven new indium borate compounds were synthesized under extreme reaction conditions. Besides several different analysis methods, the main characterization was done via X-ray diffraction. Altogether, this cumulative work yielded nine publications in international journals. The main goal of the didactics part was the development of new experiments and teaching resources regarding the topics light, luminescence and LED. On the basis of these subjects, a workshop of several hours was developed and afterwards tested in a school laboratory.
