Polarization memory effect of ultrafast infrared photoluminescence is presented for plasmonic gold nanoparticles. Our experimental results showed that the polarization direction of the ultrafast infrared photoluminescence from the rod-shaped gold nanoparticles upon the surface plasmon resonance excitation strongly retained the polarization direction of the excitation light. The mechanism of the polarization memory effect is discussed using the model of electronic Raman scattering.
