Gold nanoparticles that selectively emit left-/right-handed light - EurekAlert
When chiral(1) gold nanoparticles(2) are irradiated with near-infrared(3) femtosecond pulses(4), visible emission of luminescence is observed. In this study, this luminescence was found to yield high selectivity for left- or right-handed circularly polarized(5) light, depending on the chirality of the nanoparticles, with a dissymmetry factor(6) of approximately 0.7. This finding suggests the potential to elevate various applications using circularly polarized light to practical levels.
