| abstract | The present disclosure provides a photocathode comprising: a photocathode substrate; a metal nanoparticle film deposited on the photocathode substrate; and antimony alkali metal compound, prepared on the metal nanoparticle film; also provided is a method for preparing the photocathode, comprising: 1. depositing a layer of metal nano particle film on the surface of the photocathode substrate; 2. heating the photocathode substrate deposited with the metal nano particle film by using a heating body to ensure that the photocathode substrate is fully degassed at the temperature of over 800 ℃; 3. heating by a heating body to evaporate antimony in an antimony source to the surface of the prepared metal nano particle film to form an antimony film; and 4, heating the alkali metal source and the reducing agent through the heating body, and simultaneously heating the photocathode substrate through the heating body, so that the generated alkali metal steam is emitted onto the photocathode substrate to react with the antimony film generated in the step 3 to prepare the photocathode, thereby relieving the alkali metal evaporation problem of the photocathode of antimony alkali metal compound under the action of strong light and improving the quantum efficiency of the photocathode. |
