We propose an efficient scheme for deterministic one-step generation of three-particle Greenberger-Horne-Zeilinger (GHZ) state in a bimodal cavity based on quantum Zeno dynamics, which reduces the complexity of the experiment operations. The cavity modes are not excited in the evolution and the influence of atomic spontaneous emission and the cavity decay is also discussed by numerical calculation. The results demonstrate that the scheme is robust against the cavity decay.
