摘要

提出了一種基于圖像動態光散射原理測量二維納米顆粒粒度的新方法,稱為平移轉動-圖像動態光散射(TR-IDLS)法。采用會聚的偏振高斯光束照射樣品池中處于布朗運動的二維納米粒子,分別采集納米粒子的水平偏振散射光信號和垂直偏振散射光信號。根據兩個偏振方向上散射光光強波動的時間相關函數,計算出納米顆粒的平移和轉動擴散系數的分布,進而從擴散系數中獲得顆粒的長寬比、等效直徑和厚度的分布。采用該方法測量了球形標準納米顆粒和片狀云母顆粒的粒徑。采用電鏡獲得了片狀云母顆粒的形狀和等效直徑,并與TR-IDLS方法的實驗結果進行比較,驗證了TR-IDLS方法的可行性。

Abstract

We propose a new method to measure two-dimensional particle size of nanoparticles in imagery based on the principle of dynamic light scattering, which is called the translation-rotation image-dynamic light-scattering (TR-IDLS) method. The nanoparticles in Brownian motion in the sample pool are illuminated by a focused polarized Gaussian beam; then, the horizontal and vertical polarized scattering signals of the nanoparticles are recorded. According to the time-correlation function applied to the fluctuation of scattered-light intensity in the two polarization directions, the distributions of translational- and rotational-diffusion coefficients of nanoparticles are calculated, and the aspect-ratio, equivalent-diameter, and thickness distributions are obtained. The spherical standard nanoparticles and mica-flake particles are measured by this method. The shape and equivalent diameter of the mica-flake particles obtained by scanning electron microscopy are compared with the experimental results obtained by the TR-IDLS method, thereby verifying the feasibility of the TR-IDLS method.
