Обнаружено, что воздействие лазером мощностью 10–20 мкВт вызывает термическую активацию, которая приводит к резкому увеличению интенсивности спектров КР, а также к их видоизменению. Этот эффект имеет необратимый характер, что указывает на структурные изменения в металлической оболочке. После термоактивации становится возможным регистрировать спектры при гораздо более низких мощностях возбуждения, что существенно повышает чувствительность метода.</p></abstract><trans-abstract xml:lang="en"><p>In this study, the enhancement of Raman scattering spectra (RS) of individual dielectric (polystyrene) microspheres, coated with a thin (10 nm) metallic shell, deposited on silver-coated cover glasses, was investigated. It was found that laser irradiation with a power of 10–20 μW induces thermal activation, which leads to a sharp increase in the intensity of RS spectra, as well as their modification. This effect is irreversible, indicating structural changes in the metallic shell. After thermal activation, it becomes possible to record spectra at significantly lower excitation powers, which substantially enhances the sensitivity of the method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гигантское комбинационное рассеяние</kwd><kwd>диэлектрические микросферы</kwd><kwd>плазмонный резонанс</kwd><kwd>усиление электртческого поля</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface-enhanced Raman scattering</kwd><kwd>dielectric microspheres</kwd><kwd>plasmon resonance</kwd><kwd>electric field enhancement</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (РНФ), проект № 23-19-00788, https://rscf.ru/project/23-19-00788/.
