In this study, the LSPR effect of silver nanoparticles is investigated, and its application in deep ultraviolet LEDs is explored. Through the coupling between the nanoparticles and the substrate, the silver nanoparticles exhibit the localized surface plasmon resonance-enhanced characteristics on the spectrum. By adjusting the parameters such as the morphology and size of the silver nanoparticles, the optimization of the plasmon resonance peak and intensity can be achieved. In addition, it is found that the silver nanoparticles in the emission region of deep ultraviolet LEDs reduce optical absorption and weaken the localized surface plasmon resonance effect on the spectrum. Therefore, the application of silver nanoparticles on deep ultraviolet LEDs requires the optimization and design of silver nanoparticles to achieve the best enhancement effect. In summary, this research provides a new approach and method for the optical enhancement of deep ultraviolet LEDs.Keywords: Silver nanoparticles; Localized surface plasmon resonance effect; Deep ultraviolet LEDs; Optical enhancement.
