High-loading ultrastable CsPbBr3 perovskite quantum dots in hierarchical silicalite-1 by elimination of co-templates for multimodal optical applications

Hierarchical silicalite-1 co-templated by carbon nanotube and tetrapropylammonium hydroxide was used to confine CsPbBr 3 PQDs, showing multiple functions for optical thermometry, fingerprint identification, Fe 3+ detection and anti-counterfeiting.
