We report a high stability pH-responsive sensor based on group IV metal oxide (ZrO2 and HfO2) functionalized porous silicon (pSi). These hybrid metal oxide-pSi (MOx-pSi) materials were tested during repeated pH 2-12 cycling and during continuous UV illumination. The photoluminescence (PL) response proved to be fully reversible unlike uncoated pSi. The MOx-pSi sensor platform was also stable for at least three years.
