The invention belongs to the field related to optoelectronic technology and discloses a novel phase-change electrically-controlled photonic neuron device and a preparation method and an application thereof. The device includes a substrate, a waveguide layer, a phase-change material layer, and a heating layer. A chemical formula of the phase-change material layer is SbTe, where x+y=1 and 0.6<y<1. The phase-change material layer has a Te phase and a SbTephase embedded in the Te phase to form an island structure. When a temperature of the heating layer rises, the Te phase changes from a crystalline state to an amorphous state or a molten state, while the SbTephase maintains a crystalline state. When the temperature drops, the Te phase spontaneously crystallizes at low temperature with the crystalline SbTephase as a nucleation site simulating the process of spontaneously returning to a resting potential of neurons.
