(a) Change in the photocurrent under UV light irradiated from a flame (the distance between the photodetector and flame was ca. 1 m. (b) Digital images (snapshots from Movie S1, Supplementary Information) showing the operation of the flame alarm using a NMe2-GQD@GFET hybrid photodetector. (i) Schematic of the prototype flame alarm. (ii) The green-LED of the fire alarm was turned on when the flame was detected.
