The nanosecond excited state temporal and spectral relaxation of a purified, red-emitting DNA-templated silver nanocluster (DNA–AgNC) was characterized as a function of temperature. The findings are explained by introducing a phenomenological electronic structure diagram. The reproducibility and cyclability of the average decay time opens up the possibility of using DNA–AgNCs for decay time-based nanothermometry.

发红光的DNA模板银纳米团簇的温度依赖性激发态弛豫

纯化的，发红光的，以DNA为模板的银纳米簇（DNA-AgNC）的纳秒激发态在时间和光谱上的弛豫与温度有关。通过引入现象学电子结构图解释了这一发现。平均衰变时间的可重复性和可循环性为基于DNA-AgNCs的基于衰变时间的纳米温度计提供了可能性。
