About theoretical peculiarities of lowest excitations in modified nanodiamond color centers
The moderate-size carbon nanoclusters with paramagnetic color centers are studied by using a rather good-working simplified scheme of CNDOL type. Various electronic structure aspects of the clusters are studied. These are the localization of molecular orbitas, the electronic excitation localization...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The moderate-size carbon nanoclusters with paramagnetic color centers are studied by using a rather good-working simplified scheme of CNDOL type. Various electronic structure aspects of the clusters are studied. These are the localization of molecular orbitas, the electronic excitation localization and charge-transfer structure of the lowest triplet-triplet transitions, spin density distributions and spin correlations in the ground and excited states. The comparison is made between the respective characteristics of the diamondoid with nitrogen-vacancy (NV⁻) and oxygen-vacancy color centers. It is shown that in the asymmetrical NV⁻ center, significant variations of excitation localization and charge/spin transfer take place whereas the energetic properties vary slightly. |
