Highly stable and luminescent formamidinium-based perovskite nanocrystal probe for temperature and mercury sensors and in vitro imaging in live cells

Abstract

Silica and PMMA-coated Cs-doped FAPbBr3 nanocrystals exhibit superior stability, enabling temperature and mercury-ion sensing. The nanocrystals were also tested as a fluorescent probe to detect Hg-ions inside mammalian cells.
