研究目的
Investigating the effects of AL-TiO2-Ag Bimetallic Nanoparticle on the luminescent properties of perovskite light-emitting diodes (PeLEDs) to improve their performance.
研究成果
The simulation demonstrated that AL-TiO2-Ag Bimetallic Nanoparticle can significantly enhance the luminescence efficiency of PeLEDs by approximately 40%. The study highlights the potential of applying Bimetallic Nanoparticles to optoelectronic devices in the future.
研究不足
The study is based on simulation, and real-world application may present challenges not accounted for in the model. The effect of metal nanoparticles on the periodic structure of ZnO and potential leakage current was noted but not deeply explored.
1：Experimental Design and Method Selection:
The study simulated a PeLED with a quasi-core/shell structure using finite difference time domain (FDTD) analysis to investigate the plasma coupling effect of AL-TiO2-Ag Bimetallic Nanoparticle.
2：Sample Selection and Data Sources:
Optical parameters of various materials were imported into the Material Database from literatures.
3：List of Experimental Equipment and Materials:
The structure included Glass, ITO, ZnO, Al–TiO2–Ag Bimetallic Nanoparticle, MABr, CsPbBr3, NiO, and AL electrode.
4：Experimental Procedures and Operational Workflow:
The thickness of each film layer was set, and the size of the simulation region was defined. The dipole was chosen as the radiation source.
5：Data Analysis Methods:
The electric field distribution and the normalized radiated power were analyzed to evaluate the effect of NP on the radiative decay rate.
