WebMar 9, 2024 · XRD and XPS characterization techniques were used to confirm the formation of Bi 2 O 3 on the bismuth surface. The film showed good pH sensing behavior, with sensitivity of 51.32 mV/pH. The nanostructured bismuth oxide film was analyzed for pH sensing on the EGFET-based pH sensor platform. WebHowever, from the above data we see that the binding energy values for the various oxides overlap somewhat. The only good spectrum of an oxide I've taken is that for a sputtered cleaned surface that was then exposed to air for 1 minute. A peak at 138.1 eV was recorded for this oxide with a FWHM of 1.26 eV (at 20 eV pass energy).
