Transparent examples : Optical resins containing dispersed gold nanoparticles (AuNPs) can be prepared by the title method. The obtained light‐yellow AuNPs/thiourethane resins contain nanoparticles less than 1 nm in diameter and show good transparency and fluorescence at 690 nm (see picture). The analogous urethane resins are transparent with a red color arising from the surface plasmon absorption of the AuNPs.
