Abstract
In recent years, nanowires have been proven efficient to enhanced IR absorption of molecules and opened prospects of new ultrasensitive IR sensors. The development of integrated components requires the use of special IR glasses such as chalcogenide or silver halide glasses. In this study, we report the fabrication of a surface enhanced IR absorption substrate composed of nanowires deposited onto a chalcogenide glass slide. It enabled us to detect 4-nitrophenol at the femtomolar level and enhancement factor close to 106 was calculated.
