Zusammenfassung:	The utility model provides a sensor based on a semi-hollow metal nano-cavity dimer, which is used for solving the technical problems that the local plasmon resonance increases the spectral line width and is not beneficial to the improvement of the sensitivity of the sensor due to the fact that the radiation attenuation is greatly enhanced along with the increase of the particle size. The silver-gold nano plate comprises a silver nano plate body, a gold shell layer is arranged on the silver nano plate body, a silver-gold nano plate body is formed, and a semicircular hole is formed in the bottom of the silver-gold nano plate body. And the upper parts of at least two same silver-gold nano-plates are oppositely arranged, and a gap is formed between the upper parts of the at least two same silver-gold nano-plates to form a silver-gold nano-cavity dimer. According to the utility model, the asymmetric metal nanocavity structure has the characteristic of a plurality of plasmon resonance modes, and the coupling of a p
