Multi-energy resonance transfer protein as well as preparation method and application thereof

The invention provides a multi-energy resonance transfer protein as well as a preparation method and application thereof, and particularly, the multi-energy resonance transfer protein has the following characteristics: when the multi-energy resonance transfer protein is irradiated by incident light with a first wavelength W1, the incident light with the first wavelength W1 is irradiated by the incident light with the second wavelength W2; the multiple energy resonance transfer protein performs resonance transfer on the energy of the incident light of the first wavelength and emits emitted light of a second wavelength W2, the first wavelength W1 is 220-470 nm, and the second wavelength W2 is 380-580 nm. The invention also provides a preparation method and application of the energy resonance transfer protein. The protein provided by the invention can absorb ultraviolet light and blue light in a partial wavelength range, and has the advantages of wide wavelength absorption range and high conversion efficiency. 本
