Abstract

Herein, a one-step fabrication of disposable visual UVC sensors based on MB/PMMA thin films (thickness ~0.2–0.3 mm), comprising silver (Ag) and gold (Au) nanoparticles, was achieved. The fabricated thin films were characterized by means of XRD and SEM. Results showed the formation of Au and Ag nanoparticles in prepared films. UVC sensing behavior was investigated under the illumination of 254 nm light by following the color discharge of MB dye. A faster decolorization response was observed in Ag-MB/PMMA UVC sensor film, in which the color discharging rate was almost two times higher than MB/PMMA film. On the other hand, the Au-MB/PMMA UVC sensor film exhibited a slower response, as compared with the MB/PMMA film. The fabricated UVC sensor is expected to be highly applicable in modern sensing devices.
