Abstract (en)

[origin: WO2017051318A1] Method for the production of high efficiency photocathodes for ultraviolet based on nanodiamonds, comprising providing a support (10; 20, 21) capable of conducting electrons, and producing a photosensitive layer of nanodiamonds (30) on the support (10; 20, 21). Production of the photosensitive layer includes providing nanodiamond particles in the form of powder, hydrogenating the nanoparticles in a H2 plasma, preparing a dispersion of the hydrogenated particles in a solvent, and spraying the dispersion onto the support and waiting for the solvent to evaporate from the support, the spray and waiting cycle being repeated several times in order to obtain a continuous photosensitive layer.
