Luminescence in synthetic boromullite prepared by combustion synthesis

Boromullite is a mineral containing oxides of aluminium, boron and silicon with the chemical formula Al9BSi2O19. It has been known for more than two decades, yet it has not been explored for luminescence. We succeeded in obtaining the synthetic Boromullite by the combustion method. Activators Europium and Cerium could be incorporated during the preparation. Typical features of Ce3+, Eu3+ and Eu2+ could be observed. To the best of our knowledge, these are the first observations of luminescence in Boromullite. These studies on synthetic material can help in studying the natural minerals, e.g. in identifying using fluoroscopy.

Automated summary

In this study, synthetic Boromullite was successfully obtained by the combustion method, and its luminescence properties were observed for the first time. The research on synthetic materials can contribute to further studies on natural minerals.
