Abstract
A yolk/shell composite consisting of an AuNR core and an NdO shell with a 19 nm gap is synthesized by a multi-step over-growth method. The near-infrared luminescence of AuNR@NdO is up to 4.6 times higher than that of NdO hollow nanoparticles. The underlying mechanism of plasmon-induced luminescence enhancement is further investigated.
摘要
通过多步过度生长法合成了一种由金纳米棒（AuNR）核和具有19纳米间隙的氧化钕（NdO）壳组成的蛋黄/壳复合材料。金纳米棒@氧化钕（AuNR@NdO）的近红外发光比氧化钕空心纳米颗粒的发光高4.6倍。进一步研究了等离子体诱导发光增强的潜在机制。
