The invention discloses a fluorescent nano-material and a preparation method and application thereof. The nano-material has specific selective response to thionyl fluoride, and construction units are self-assembled and gathered into a micro cross network structure with nanobelts through pi-pi stacking; the fluorescent nano material prepared by the preparation method has a uniform nanobelt structure, the form of the fluorescent nano material is regular and uniform, and a high-speed transmission channel is provided for energy transfer among molecules by virtue of a radial net structure formed by mutually connecting nanobelts; meanwhile, the large specific surface area is beneficial to adsorption and diffusion with thionyl fluoride poison gas, the detection sensitivity of the fluorescent nano material is improved, and the fluorescent nano material has no fluorescent response to phosgene, sarin poison gas, tower collapse poison gas, disulfur decafluoride, oxygen difluoride and the like, has very good anti-interfe
