Color indicating film to detect ethylene (C2H4) gas was fabricated by depositing SiO2 nanoparticles and the indicating solution synthesized with palladium sulfate as well as ammonium molybdate on the filter paper. The color of indicating film without SiO2 was easily changed from white to blue in air because PdSO4 remarkably accelerates the redox reaction of ammonium molybdate, which generates molybdenum blue reaction. In this study, we successfully diminished the color change of indicating film in air by controlling the amount of SiO2 on filter paper using a layer-by-layer (LBL) self-assembly method. The color of prepared indicating film with 30 PDDA/SiO2 bilayers was maintained to be white in air. When this indicating film was exposed to C2H4 (50–150 ppm), the Hunter values ($L$, $a$, and $b$) were gradually decreased until 8 days and then maintained. The color of indicating film was changed from white to dark blue.
