Formation and structure of B28N28 clusters studied by mass spectrometry and molecular orbital calculation

摘要

Boron nitride (BN) nanocage clusters of B28N28 were synthesized, and detected by laser desorption time-of-flight mass spectrometry. The B28N28 clusters consisted of 4- and 6-membered BN rings satisfying the isolated tetragonal rule, which was optimized by molecular orbital calculations. The electronic structure showed a bandgap energy of 5.2 eV. (C) 2004 Elsevier Ltd. All rights reserved. [References: 21]
