Straightforward encapsulation of ultrastable CsPbBr3 PQDs and rare-earth emitters in zeolite for ratiometric temperature sensing and wet fingerprint recognition

All-inorganic metal halide perovskite quantum dots (PQDs) hybrids with high stability, multi-model emission and responsive luminescence are of great importance for optical applications. Herein, a dual-emitting CsPbBr 3 /Si-1:Eu 3+ composite was successfully...
