单分子光谱显微术：亚衍射折射法的入门
Single-molecule spectromicroscopy: the door into sub-diffraction refractometry
摘要：
提出了一种利用单分子光谱探测固体中折射率$n$局域涨落的新方法。它是基于固体中染料中心的有效辐射寿命$T_1$对$n$的依赖性$T_1(n)$。超低温下SM零声子谱线的探测给出了SM自然谱线宽度（与$T_1$成反比）的值，并使揭示固体中局部$n$值的分布成为可能。在这里，我们证明了这种可能性的例子，无定形聚乙烯和多晶萘掺杂与三萘嵌苯。
英文摘要：
We suggest a novel approach for probing of local fluctuations of the refractive index $n$ in solids by means of single-molecule (SM) spectroscopy. It is based on the dependence $T_1(n)$ of the effective radiative lifetime $T_1$ of dye centres in solids on $n$ due to the local field effects. Detection of SM zero-phonon lines at ultra-low temperatures gives the values of SM natural spectral linewidth (which is inverse proportional to $T_1$) and makes it possible to reveal the distribution of the local $n$ values in solids. Here we demonstrate this possibility on the example of amorphous polyethylene and polycrystalline naphthalene doped with terrylene.
