A photoluminescence (PL)‐based oxygen and glucose sensor utilizing inorganic or organic light emitting diode as the light source, and polythiophene:fullerene type bulk‐heterojunction devices as photodetectors, for both intensity and decay‐time based monitoring of the sensing element’s PL. The sensing element is based on the oxygen‐sensitive dye Pt‐octaethylporphyrin embedded in a polystyrene matrix.
