This research contributes to work on synthesizing zinc oxide nanoparticles (ZnO NPs) at room temperature (RT) and their utilization in flexible gas sensors. RT ZnO NP synthesis with a basicity solution (pH ≈ 13) demonstrates an efficient method for well-crystalline NPs (RT.pH13) comparable those synthesized by the hydrothermal (hyd.C). The RT.pH13 achieved high thermal stability minimal organic reside impurities (~4.2 wt%), 30–80 nm particle size distribution, specific surface area (14 m2 g−1). pre- post-calcinated were then incorporated into sensors sensing applications ambient conditions (RT relative humidity of 30–50%). pre-calcinated ZnO-based sensor demonstrated superior sensitivity styrene acetic acid lower dimethyl-6-octenal. calcinated (RT.pH13.C) exhibited acid, but heightened benzene, acetone, ethanol. suggests correlation between structural transformations following calcination. investigation mechanisms highlighted role properties sensors’ affinity molecules variations. study further explored mechanical flexibility, which is crucial Internet Things (IoT) applications.

Abstract In recent years, the gas sensor technology has experimented an interesting growth due to device improvements driven by nanostructured semiconductor films. Nanostructured sensors have enabled possibility of reducing operation temperature at room levels, which implies a significant reduction on power consumption, as well develop over flexible substrates. Therefore, in this work, fabrication using solution-processing technologies is presented. ZnO mesoporous fibres decorated with Carbon-Quantum-Dots been used active layer, and electrical response, measured ratio between resistance target respect air, Furthermore, interdigitated electrode configuration for finger spacing 0.2, 0.4 0.6 mm. A maximum response 0.016 was achieved.
