CsPbBr3 perovskite quantum dot decorated ZIF-8 MOF: a selective dual recognition fluorometric visual probe for 4-nitroaniline and rhodamine blue

Stable and fluorescent ZIF-8 confined CsPbBr 3 perovskite were synthesized to act as a dual functional luminescent probe for the sensing of 4-nitroaniline and rhodamine blue dye. The paper sensor shows visual recognition ability of the analytes.
