The fluorescent fabric refers to a fabric with strong light reflection effect after common fabric is subjected to fluorescent dyeing or coating finishing. The fluorescent fabric can lead the far-away target or the target in the dark to obtain strong reflection light, thereby playing a good role in warning and safety prevention. At present, the fluorescent fabric mainly uses chemical fibers, cotton and hemp basically adopts fluorescent paint to achieve the dyeing purpose through an adhesive, and is mainly an organic luminescent material, and compared with the luminescent organic material, the lanthanide compound luminescent material is attracting more and more attention due to the fact that the luminescent material has larger Stokes displacement, narrower linear emission and longer service life.
The polyoxometallate is a nano-metal oxygen cluster with a definite structure, and has rich metal elements and diversified frameworks. Importantly, polyoxometallates are an important class of inorganic ligands that can coordinate with lanthanoids to improve their luminescence properties, and therefore lanthanide polyoxometallates are excellent building blocks for building intelligent luminescent materials.

s2, treating the cotton fabric obtained in the step S1 in a polyacrylamide solution, washing with distilled water, drying, treating with a europium tungstate solution, washing with distilled water, and drying;
S3, repeating the step S2 for 1-5 times to obtain the photoluminescence fabric.
Further, in the step S2, the treatment in the polyacrylamide solution is specifically that the treatment is immersed in the polyacrylamide solution for 30min.
Further, in the step S2, the treatment by using the multi-europium tungstate solution is specifically that the multi-europium tungstate solution is immersed for 30min.
Further, the europium tungstate is Na 9EuW10O36.
In step S2, the concentration of the polyacrylamide solution is 5-35 g/L.
Further, in the step S2, the europium tungstate solution is 10-90 g/L.
Further, the temperature of the drying is 60 ℃.
The invention also provides the photoluminescent fabric prepared by the preparation method.
Compared with the prior art, the technical scheme provided by the invention has the advantage that the europium decatungstate anion (EuW 10O39]9-) has excellent luminous performance. In the structure, eu 3+ ion coordinates with two [ W 5O18]6- ligands, presents typical emission characteristic peak of Eu 3+, and simultaneously has energy transfer from Eu 3+ ion to [ W 5O18]6- ], and the introduced polyelectrolyte can interact with negative charge polyoxometallate through electrostatic interaction, so that the polyelectrolyte is fixed on fabrics, and the fabrics have excellent photoluminescence performance.
