Зарегистрирована зависимость амплитуды наведенных изменений в области ППРП от толщины диэлектрических пленок Na3 AlF6 , разделяющих монослои наночастиц серебра. Обнаружено существенное увеличение амплитуды оптического отклика (до 80 %) для наноструктуры с четвертьволновыми прослойками Na3 AlF6 . Характеристические времена релаксации наводимых изменений при энергиях возбуждения 5–10 мкДж для наноструктур с различной толщиной диэлектрических прослоек Na3 AlF6 практически не изменяются, составляют ~2 пс и совпадают с временными параметрами кинетического отклика, характерными для используемого монослоя наночастиц Ag. </p></abstract><trans-abstract xml:lang="en"><p>The features of the induced changes in the optical density spectra of multilayer Ag-Na3 AlF6 nanostructures under a femtosecond laser pulses exitation in the band of surface plasmonic resonance of absorption (SPRA) were studied. The dependence of the amplitude of the induced changes on the thickness of the dielectric Na3 AlF6 films separating the monolayeres of silver nanoparticles was registered. A significant increase of the optical response amplitude (up to 80 %) was found for the nanostructures with the quarter-wavelength Na3 AlF6 interlayers. For nanostructures with different-thickness dielectric Na3 AlF6 interlayers the characteristic relaxation times of induced changes at an excitation energy of 5–10 μJ do not practically vary, are equal to ~2 ps and coincide with the kinetic response time parameters of the used silver nanoparticle monolayers. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>ультракороткие лазерные импульсы</kwd><kwd>динамика электронных возбуждений</kwd><kwd>плотноупакованные наноструктуры</kwd><kwd>поверхностный плазмонный резонанс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultrashort laser pulses</kwd><kwd>dynamics of electronic excitations</kwd><kwd>densely packed nanostructures</kwd><kwd>surface plasmonic absorption resonance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Electron dynamics in metallic nanoparticles / J.-Y.
