We theoretically investigate the influence of metallic nanoparticles on light emission in silicon light-emitting diodes (LEDs) by an improved effective mode volume model proposed in this paper. We show that an enhancement of the radiative efficiency of silicon LEDs can be achieved by localized surface plasmons on silver (Ag) nanoparticles. The calculated result of optimal Ag nanoparticle size to enhance light emission of silicon LEDs at 900 nm wavelength is in very good agreement with those obtained from the experimental results.
