Abstract

The suitability of amorphous boron carbon nitride that was deposited by dual gun magnetron sputtering of graphite and boron nitride targets, as a ph sensor was investigated. Stable and reproducible drain currents were produced as a function of reference electrode potential by amorphous borob carbon nitride when dipped in standard phosphate solutions in order to be effective as the ph sensor. The sensitivities of the sensor were estimated to be in the range of 40 mV/pH. The response time of the sensors was found to be reasonable in the range of a few seconds and demonstrated a good stability of the sensing membrane by remaining stable for at least over a period of 10 min in the phosphate solution.
