摘要：
A yolk/shell composite consisting of an AuNR core and an Nd2O3 shell with a 19 nm gap is synthesized by a multi-step over-growth method. The near-infrared luminescence of AuNR@Nd2O3 is up to 4.6 times higher than that of Nd2O3 hollow nanoparticles. The underlying mechanism of plasmon-induced luminescence enhancement is further investigated.
