The invention relates to a fluorescent powder slurry for plasma display and the formation method on shadow mask, belonging to the technical field of flat panel TV set. The inventive slurry consists of fluorescent powder, organic resin, organic solvent and nanopowder, wherein the fluorescent powder accounts for 40-50 percent of the total weight, the organic resin accounts for 3-6 percent of the total weight, the organic solvent accounts for 45-55 percent of the total weight, and the nanopowder accounts for 0.5-3 percent of the total weight. The proper amount of nanopowder (0.5-3 percent) added into the fluorescent powder slurry can effectively improve the dispersion and the suspension properties of the fluorescent powder in the slurry and can well improve the thixotropy of the fluorescent powder slurry so as to ensure that the slurry viscosity decreases during printing to obtain adequate feeding amount and also ensure that the slurry can rapidly regain the high viscosity and settle at the periphery of small holes other than flowing out when the slurry is printed to the holes of the shadow mask. Meanwhile, the slurry can be oven-dried and sintered after the printing process such that the nanopowder is filled into the gap between particles of fluorescent powder, thereby well bonding the fluorescent powder particles and preventing powder loss resulting from insufficient bonding force of the fluorescent powder.
