To analyze the contribution of light-absorption and light scattering of silver nanoparticles to the localized surface plasmon resonance (LSPR) effect, poly(3,4-ethy lenedioxythiophene) polystyrene sulfonate was doped with TAgNPs or AgNDs at the same concentration (1.17 lg/cm(2)) and made into polymer light-emitting diodes (PLEDs). According to the current densityvoltageluminance characteristics and electroluminescence (EL) spectra, the enhancement factors for current efficiency and EL intensity for AgND-containing PLEDs were found to be higher than those for PLED with TAgNPs by 24.9% and 138%, respectively. This shows that the metal nanoparticles with higher light scattering property can induce a relatively strong LSPR effect, which possibly gives a hint to design plasmonic photovoltaic in future.
