Показано, что на различных длинах волн видимого диапазона спектра величина полной скорости спонтанного перехода в молекуле, находящейся на оптимальном расстоянии по отношению к структуре из кремниевых наносфер и при оптимальных размерах структуры, может быть в 5–10 раз меньше по сравнению со скоростью перехода при отсутствии наночастиц.</p></abstract><trans-abstract xml:lang="en"><p> The article discusses the issues of inhibition of spontaneous emission of molecules by using silicon spherical nanoparticles and dimers made from them. It is shown that at different wavelengths of the visible spectral range, the value of the total spontaneous transitions rate in a molecule located at an optimal distance with respect to the structure with silicon nanospheres and at an optimal size of the structure can be up to 5–10 times lower than the transition rate in the case when the nanoparticles are absent.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>замедление спонтанного испускания</kwd><kwd>диэлектриомления</kwd><kwd>димер наночастиц</kwd><kwd>ческая наночастица с большим значением показателя прелфотовольтаика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inhibition of spontaneous emission</kwd><kwd>dielectric nanoparticle with a high refractive index</kwd><kwd>dimer of nanoparticles</kwd><kwd>photovoltaics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Белорусского республиканского фонда фундаментальных исследований (проект № Ф19МС-004).</funding-statement><funding-statement xml:lang="en">The work was supported by the Be- la rusian Republican Foundation for Fundamental Research (project no.
