Halide perovskites (ABX3) have advantages of high photoluminescence quantum yield (PLQY), high gain coefficient, high carrier mobility and tunable bandgaps, which has great development potential and application prospects in tunable photoelectronic devices. However, blue emission perovskite LEDs lag behind their red and green counterparts in efficiency due to its high defect density and difficulties of maintaining quantum efficiency, which greatly restricts the development of the white light LEDs and display devices. Localized surface plasmon resonance (LSPR) can cause the resonant interactions of electromagnetic waves and free electrons in solid-state materials that have demonstrated great advantages in the field of Raman mapping, photodetector and laser. In addition, photoelectric properties of materials can also be manipulated by it that has great advantages for tunable photoelectric devices. In this work, the finite difference time domain (FDTD) method was used to simulate the extinction spectra of Au or Ag nanoparticles on SiO2, as well as study the influences of the shape of the nanoparticles on the position of extinction spectral peak. Then the influence of luminescence efficiency of the blue emission perovskite was analyzed by this model. Finally, the optimal optical enhancement structure of BE perovskite was obtained. According to the simulation results, compared with Au and Ag solid spheres, the Ag hollow sphere not only has the best optical enhancement effect on blue emission perovskite, but also has wide tunable ranges that can cover the entire optical band. Therefore, based on the regulation sensitivity of the Ag hollow spheres in the optical band, it provides an effective solution and simulation results for the performance optimization of perovskite-based tunable photoelectronic devices.
