The invention discloses a plasma resonance enhanced blue organic light emitting diode and a fabrication method thereof. The blue organic light emitting diode sequentially comprises an ITO glass substrate, a hole transmission layer, a spinning blue light emitting layer, an evaporation blue light emitting layer, an electron transmission layer, metal nanoparticles, an electron transmission layer, an electron injection layer and an opaque metal negative electrode from bottom to top. The fabrication method comprises the steps of firstly, cleaning the substrate; secondly, performing spinning to fabricate a film; and finally, performing evaporation in vacuum to fabricate the film, and performing cooling after completion. A spinning/evaporation dual-blue light layer is employed, the advantages of two film fabrication methods of spinning and evaporation are compatible, so that the diode is easy to fabricate and is relatively high in efficiency. Silver nanoparticles are added into the electron transmission layers and are placed at a place near to the negative electrode, electron injection is improved by nanoparticle plasma resonance, meanwhile, the trap effect of the metal nanoparticles is effectively reduced, and finally, the performance improvement of the diode is achieved. The blue organic light emitting diode is simple and practical, and has potential application value.
