Coating of upconversion nanoparticles with silica nanoshells of 5–250 nm thickness

Coating of upconversion nanoparticles with silica nanoshells of 5–250 nm thickness

A concept for the growth of silica shells with a thickness of 5–250 nm onto oleate-coated NaYF4:Yb3+/Er3+ upconversion nanoparticles (UCNP) is presented. The concept enables the precise adjustment of shell thicknesses for the preparation of thick-shelled nanoparticles for applications in plasmonics...
