  • Method for preparing sodium interface and method for preparing sodium-based optical structure device
    Patent number: 11761093
    Abstract: The present invention discloses a method for preparing a sodium interface and a method for preparing a sodium-based optical structure device. This sodium interface is prepared in an inert gas atmosphere by the following steps: (1) melting solid sodium metal into liquid by heat, and stripping off solid oxides and impurities on the surface of the molten sodium metal to obtain pure liquid sodium with metallic luster; and (2) spin-coating a dielectric substrate with the liquid sodium to obtain the sodium interface tightly attached to the dielectric substrate. The prepared sodium interface can be used as a plasmon polariton material for use in plasmon polariton optical waveguides, nano-lasers and the like.
