Optical properties
Selective resonance enhancement of Raman scattering intensity in photoinduced nonradiative charge transfer
B. Kh. Bairamov Ioffe Institute, St. Petersburg
Abstract:
This paper reports on the formation of complexes consisting of isolated free-standing crystalline semiconductor quantum dots, for example, $nc$-Si/SiO$_2$, functionalized by short oligonucleotides, for example, the single-stranded system $d$(20G, 20T). Here, $d$ are deoxyribonucleotides, G and T are guanine and thymine nucleotides, respectively. It has been found that these complexes are unique objects for the elucidation of the specific features in the manifestation of new quantum-size effects in biomacromolecules. It has been demonstrated that the possibility exists of detecting and recording, in such complexes of biomacromolecules, spectrally selective resonance enhancement of Raman scattering intensity in fluctuations of nucleotide molecules due to coherent nonradiative transfer of a photoexcited electron and a hole at the interface of the complex. This dynamic optical imaging of spectral responses can be of applied interest for the development of nanobiophotonic technologies.
