The invention discloses a blue light organic light emitting diode structure and a preparation method thereof which utilizes the plasmon resonance effect of silver nanocubes to enhance device performance. Cubic layer, blue light emitting layer, electron transport layer, metal cathode. The introduction of silver nanocubes can effectively improve the performance of blue organic light emitting diodes. The preparation process includes: firstly adopting a synthetic method to prepare silver nanocubes, and then wrapping the silver nanocubes with a silicon dioxide layer. The preparation of the device is to clean the substrate first, then spin-coat to form a film, and then evaporate to form a film in a vacuum, and then cool it after the end. In the invention, the silver nanocube is spin-coated between the hole transport layer and the blue light emitting layer, and the efficiency of the blue light organic light emitting diode is effectively improved by utilizing the strong plasma resonance effect of the silver nanocube. The invention is simple and easy to implement, and has potential application value. |
