摘要/Abstract

摘要：引入不同孔径的光纤传输激光和散射光子，不同孔径的Y形光纤传输入射光和散射光，采用光子相关光谱法（PCS）设计了纳米颗粒测量系统.讨论了光纤芯径、显微物镜的数值孔径、温度和散射角度对测量结果的影响.实验结果表明，温度在13~22 ℃超净间中，该系统能准确地测量纳米颗粒粒度.

Abstract: Different aperture fiber were applied for transmission of laser and scattered photons,different aperture y-type fiber were used for transmission of incident and scattered light synchronously.Based on photon correlation spectroscopy the nanometer particle measuring system was designed.Besides,the affects of fiber core diameter,microscope objectives numerical aperture,temperature and scattering angle were discussed.Experiments show that it is accurate and stable for nano-particle size distribution measurement,all experiments were finished in super clean room,in which temperature was controlled at about 13~22 ℃.

Key words: photon correlation spectroscopy (PCS), nano-particles, measurement system, single scattered system, double scattered system
