Abstract:
1. An optical sensor for detection of an analyte of interest, said optical sensor comprising: a first substrate; a hydrogenated amorphous silicon carbon layer having a plurality of gaps on said first substrate; a plurality of strips of transparent electrode on a portion of said hydrogenated amorphous silicon carbon layer and on a portion of said first substrate within said gaps; a photodetector for detecting photoluminescence, and arranged on at least one of said transparent electrode strips on said portion of said hydrogenated amorphous silicon carbon layer; and an excitation source for emitting electroluminescence, and arranged on at least another of said transparent electrode strips on said portion of said first substrate within said gaps; and a sensing element arranged to emit said photoluminescence to said photodetector and arranged to receive said electroluminescence from said excitation source.
