Semiconductor Gel Networks
In article number 2101628, Nadja C. Bigall and co‐workers demonstrate that a single gold nanoparticle is able to quench the fluorescence of up to 9 semiconductor nanorods in mixed, co‐gelated gel networks. Upon varying the particle number ratio of CdSe/CdS and Au nanocrystals, the spatial extent of quenching, thus, the travel distance of photoexcited electrons is changed...
In this work, mixing and co‐gelation of Au nanoparticles (NPs) and highly luminescent CdSe/CdS core/shell nanorods (NRs) are used as tools to obtain noble metal particle‐decorated macroscopic semiconductor gel networks. The hybrid nature of the macrostructures facilitates the control over the optical properties: while the holes are trapped in the CdSe cores, the connected CdSe/CdS NRs support the...
