Nanostructured Copper Iodide Film in a Multifunctional Flexible Device for Ultraviolet Photodetection and Ammonia Monitoring
Original language description
A flexible, lightweight, and portable device integrating the functions of an ammonia gas sen-sor and an ultraviolet (UV) photodetector operating at room temperature is developed usingavailable materials with no physiological toxicity and low manufacturing cost by employing thelow-temperature aqueous successive ionic layer adsorption and reaction (SILAR) method todeposit a nanostructured copper iodide (CuI) thin film on a flexible polyethylene (PE) sub-strate. Under the irradiation of UV radiation, it functions as a flexible photoconductive UVphotodetector with a photoconductivity gain of 1.17, a sensitivity of 2.3 mA/W, a specific de-tectivity of 1×109Jones and an external quantum efficiency of 0.8% with a response/recoverytime of several minutes. It is quite suitable for wearable personal UV monitoring devices andas an electronic eye in door security system. The high selective sensitivity of the device toammonia (NH3) is due to the synergistic effect of the electron donor gas NH3on the p-typesemiconductor CuI and its ability to complexing NH3. The detection limit of 0.15 ppm of theCuI/PE chemiresistive ammonia sensor and its fast response/recovery make it suitable forfood spoilage detection, real-time monitoring of ammonia leaks, and in medical diagnosis bydetecting NH3in exhaled air.
