Моделирование технологического процесса создания сферических лазеров на основе микро- и наночастиц благородных металлов, покрытых диэлектрической SiO2-оболочкой

Abstract

The study of the possibility of forming using a sol-gel method composite micro powder's based on silicon dioxide (SiO 2) containing reduced silver nanoparticles and an optically active dye in the form of fluorescein has been carried out. A model for obtaining a nanoscale spherical laser operating on the interaction of localized surface plasmons with the dye molecules is proposed. Conditions for changing the transmission optical spectra of synthesized materials resulting from the action of surface plasmons of Ag° nanoparticles on fluorescein molecules are considered.
