The experimental scheme and results of circularly polarized emission by a chiral gold nanoparticle.

Caption

(Upper panel) Experimental scheme. When a chiral gold nanoparticle is illuminated with near-infrared linearly polarized femtosecond light pulses, circularly polarized luminescence is observed in the visible region. (Lower panels) From left to right, scanning electron micrograph of the chiral gold nanoparticle (a), microscopic image detecting the left-circularly polarized luminescence (b), and the image detecting the right-circularly polarized luminescence (c).
