Characterization of the structure and stimulated emission of spherical and cylindrical spasers

In this paper, experimental realization of the surface plasmon laser in a solution for the visible and near infrared region (VNIR) based on the hybrid nanoparticles with a 13-nanometre gold core or the nanorod with various aspect ratios surrounded by a 20–40 nm thick dye-embedded silica shell (fluorescein or DCM) was presented. The spasing in those structures using the methods of confocal microscopy, TEM was experimentally studied.
