Fabrication and investigation of a new all-inorganic lead free perovskite Cs3Bi2I6 Br3 for ammonia detection at room temperature

Field Effect Transistor Sensors Based on In‐Plane 1T′/2H/1T′ MoTe2 Heterophases with Superior Sensitivity and Output Signals

“…The sensor's responses become stabilized over time, proving the 1T′/2H sensor's long‐term stability. Figure 4f compares the NH 3 sensing results of the 1T′/2H/1T′ sensor with those from recent representative NH 3 sensors made of Ti 3 C 2 T x, [ 30 ] SnO 2 nanoparticles, [ 31 ] MoS 2 /MoO 3, [ 32 ] MoS 2, [ 33 ] NiWO 4 /CNT, [ 34 ] WS 2, [ 35 ] M‐CNTs, [ 36 ] Cs 3 Bi 2 I 6 Br 3, [ 37 ] and RGO/CuO. [ 38 ] The detection limit and operating current of our 1T′/2H/1T′ sensor outperform most of these NH 3 sensors.…”

A review on the sensing mechanisms and recent developments on metal halide-based perovskite gas sensors

“…Jiao et al used lead-free Cs 3 Bi 2 I 6 Br 3 perovskite for the detection of ammonia, acetone, and ethanol. 206 Its response toward ammonia was high at 11.8 for 500 ppm and stable for up to 14 days. This excellent sensing performance is attributed to the recoverable exchange between Cs + ions in the octahedral vacancies and an ammonia molecule.…”

“…158 The performance of gas sensors based on different metal halide perovskites is summarized in Table 1. 14,33,36,37,142,143,149,151,158–208…”

Eco-friendly MA3Bi2I9 perovskite thin films based ammonia sensor

“…This indicates that the MABI thin film-based sensor shows excellent selectivity for detecting ammonia. The gas-sensing performance of the MABI sensor compared to previous reports in the literature [58][59][60][61][62][63] is listed in table 1. The parameters listed in table 1 indicate that MABI thin-film sensors have several advantages like ambient synthesis, non-toxic nature, quick response, and recovery time compared to other ammonia sensors.…”
