Abstract
A combined pH- and redox-sensitive bi-electrode glass thin-film sensor has been developed for the simultaneous detection of pH and redox potential in aqueous solutions for the first time. The pH- and redox-sensitive glass bulk materials have been prepared and tailored by glass-pouring processes. The electrode structure (sensor chip) is fabricated via conventional thin-film techniques on glass substrate. The glass bulk materials were transferred on the electrode structures by means of pulsed laser deposition technique. The fabricated sensors have been characterized physically and electrochemically by scanning electron microscopy (SEM), Rutherford backscattering spectroscopy (RBS), profilometry, energy dispersive X-ray spectroscopy (EDX), impedance and potentiometric measurements.
