Excellent physicochemical and sensing characteristics of a Re _x O _y based pH sensor at low post-deposition annealing temperature.

ABSTRACT: pH monitoring in clinical assessment is pivotal as pH imbalance significantly influences the physiological and extracellular functions of the human body. Metal oxide based pH sensors, a promising alternative to bulky pH electrodes, mostly require complex fabrication, high-temperature post-deposition treatment, and high expenses that inhibit their practical applicability. So, there is still room to develop a straightforward and cost-effective metal oxide based pH sensor comprising high sensitivity and reliability. In this report, a novel solution-processed and low-temperature annealed (220 °C) mixed-valence (vii/vi) oxide of rhenium (Re _x O _y ) was applied in an electrolyte-insulator-semiconductor (EIS) structure. The annealing effect on morphological, st
