چکیده
In this work, the metalloporphyrin film of PtOEP/Poly (St-co-TFEMA) modified by nano Al2O3 powder was prepared, and enhancement performance oxygen sensing studied in detail. It verified that extended residence time through characterization SEM. The phosphorescence intensity changes with content PtOEP were studied. Stern-Volmer equations before after modification compared. found linearity calibration curve still high, but sensitivity value KSV significantly improved due to increase quenching probability between indicator oxygen. Finally, stability test shows Al2O3@PtOEP/Poly presents a strong anti-photo-bleaching ability, response is shortened.

The effects of UV-ozone (UVO) treatment on the sensing behaviours of extended-gate field-effect transistors (EGFETs) that use Al₂O₃ as the sensing film have been investigated. The Al₂O₃ sensing films are UVO-treated with various duration times and the corresponding EGFET sensing behaviours, such as sensitivity, hysteresis, and long-term stability, are electrically evaluated under various measur...
