The invention discloses a transparent display screen based on plasmon particles, which comprises a transparent substrate horizontally arranged, wherein a blue light display metal particle layer, a green light display metal particle layer and a red light display metal particle layer are sequentially arranged on the upper surface of the transparent substrate. The transparent display screen comprises a transparent matrix and metal nano-particle layers for realizing light intensity scattering of red, green and blue colors, wherein the metal nano-particles have wavelength selective strong resonance scattering characteristics, so that clear patterns can be displayed on the screen by projecting light near a resonance wavelength on the screen. Compared with the prior preparation method based on silver nanoparticle solution coating and drying, the preparation process has the advantages of low cost, short preparation period, convenient tuning of display wavelength and the like, and has important application value. |
