Non-stoichiometric hybrid halide perovskite film for gaseous NH₃and HCl sensing

Abstract

We report the first use of the non-stoichiometric perovskite MAPbI3 film for both NH3 and HCl detections depending different change trend in film resistance, in which moderate excess PbI2 can...

Controllable fabrication of well-shaped PMBA@CsPbBr3 nanoparticles for highly sensitive detection of HCl and HBr

“…14,15 As per previous research, lead halide perovskite NCs have enabled the development of sensitive gas sensing detectors for NH 3 or HCl. 16–18 Chen et al reported the application of CsPbCl 3 NCs as spectrochemical probes for detecting gaseous HCl; HCl vapor can be detected at concentrations as low as the safety threshold of 5 ppm. 5 Markina et al designed a halide perovskite nanowire laser, demonstrating a sensitive optical response to HCl molecules.…”
