[Press Release] Gold nanoparticles that selectively emit left-/right-handed light
Release Summary
When chiral gold nanoparticles are irradiated with near-infrared femtosecond pulses , visible emission of luminescence is observed. In this study, this luminescence was found to yield high selectivity for left- or right-handed circularly polarized light, depending on the chirality of the nanoparticles, with a dissymmetry factor of approximately 0.7. This finding suggests the potential to elevate various applications using circularly polarized light to practical levels.
