| 摘 要： | 金纳米团簇作为一类新型纳米材料具有独特的光学特性。当金纳米团簇颗粒的尺寸小到与电子的费米波长（〈1nm）相当时,由于量子尺寸效应,金颗粒会受激发射出荧光。作为一种新型荧光材料,金纳米团簇具有发光颜色随团簇尺寸可调、荧光不易猝灭等许多优势。本文主要综述了金纳米团簇的荧光性质及其在生物标记、生物成像以及生物检测等方面的应用...

| Abstract: | Au nanoclusters have emerged as a class of materials with unique optical properties.When the size of Au nanocluster decrease to comparable to the Fermi wavelength(<1nm) of an electron,it exhibits fluorescent characteristics while they are excited,which resulted from its quantum effect.As a novel fluorescent material,Au nanoclusters show size-dependent emission,a slower photobleaching rate and very good stability.The fluorescent properties of Au nanoclusters and their applications in the fields of biological... |
