Analysis of Measuring Time for Au Nanoparticle Size Measurement by Photon Cross Correlation Spectroscopy

摘要：

It introduced the basic principle of measuring the size of nanoparticles by the method of Photon crosscorrelation spectroscopy (PCCS). The measuring time for Au particle size measurement at different concentration using PCCS was studied. We measured gold particles with an average diameter of 24.5 nm at different concentration and different measuring times by PCCS. The measuring results demonstrate that for the same measuring time, the higher the concentration is, the smaller the standard deviation of repeated measurements is; for suspension of the same concentration, the longer the measuring time is, the smaller the standard deviation of repeated measurements is. It fitted the relationship between the standard deviation of measuring results and the measuring time at difference concentration. For the needed measuring accuracy, we can get the measuring time for some concentration according to the curve fitting.
