Abstract
The polarization dependence of rotational diffusion of quantum rods was investigated and characterized by analyzing amplitude and characteristic time of the correlation functions. In order to measure the polarization dependence, a polarized fluorescence correlation spectroscopy system was composed based on a microscope. From the results, the rotational diffusion region of Qrod was observed at a time range below 10-5 s, and the rotational diffusion parameters were extracted by using a rotational diffusion model. The parameters revealed the polarization dependence of rotational diffusion of Qrod in solution. We showed that polarized FCS is quite useful to investigate rotational diffusion of rod-like particles.
