Solid and hollow metallo‐dielectric spheres are created by layer‐by‐layer self‐assembly. The discrete metallic nanoparticles, which make up the shell, form a contiguous layer that exhibits a collective plasmon resonance with a splitting of the dipole mode into transverse and longitudinal modes. The splitting can be controlled by the number of self‐ assembled octa(3‐aminopropyl)silsesquioxane (NSi8) capped Ag nanoparticle (see Figure) layers deposited.
