 note = {Published in physica status solidi (b), Vol. 245, No. 12, pp2733-2736, 2008., Bi12GeO20 crystals have been performed, in addition to relativistic molecular orbital calculations. Both materials consist of the same elements but form different crystal structures. Based on the obtained results, the excitonic reflection structures and luminescence properties of Bi4Ge3O12 and Bi12GeO20 are discussed in comparison with each other., Book, physica status solidi (b). 245(12):2733-2736 (2008)},
