  Featured by prominent flexibility and fidelity in producing sophisticated
stereoscopic structures transdimensionally, three-dimensional (3D) laser
printing technique has vastly extended the toolkit for delivering diverse
functional devices. Yet chiral nanoemitters heavily resorting to artificial
structures that manifest efficient emission and tightly confined light-mater
interactions simultaneously remains alluring but dauntingly challenging for
this technique at this moment. In this work, we assert the chiral
photoluminescence is implemented from silver nanostructures of optical duality
in one go via a twofold three-dimensional laser printing scheme. Such laser
printing protocol allows the highly desired duality by simultaneously producing
uniformly distributed fluorescent silver nanoclusters and aggregated plasmonic
silver nanoparticles to tightly confine chiral interactions at the nanoscale. A
helical emitter of 550 nm-helix-diameter as fabricated has seen a record-high
luminescence anisotropic factor with the absolute value up to 0.58, which is
two orders of magnitude greater than fluorescent chiral silver clusters. This
method holds great promise for future versatile applications in chiroptical
nanodevices.
