In the present study, we report a novel and easy technique to synthesize a ZnO nanostructured porous network using activated carbon (AC) that is used as a sensor material for an interacting gas at room temperature. The formation of the material was confirmed by XRD and HRTEM image. The porous nature of the synthesized ZnO could be used to incorporate a laser dyes into it which makes it more fluorescent material. Broad absorption/excitation band(s) in laser dye (Stilbene) helps to get it excited over a range and broad fluorescent emission that enhances the sensitivity on integration. The changes in the intensities of the absorption/emission spectra of sensitized ZnO on interaction with gas molecules could be used to fabricate a gas sensor working at room temperature. |
