| Summary: | 碩士 === 國立中興大學 === 物理學系所 === 103 === Nanotechnology has been widely used in interdisciplinary fields. In order to find out more information of the characteristics in nanomaterials, the detection technologies are more and more important in the development of nanotechnology. In detection technology, the optical detection provides a nondestructive, simple, fast, qualitative and quantitative measurement.
Since the structures of most commercial instruments are considerably stable, however, they could not satisfy various experimental conditions. The purpose of this research is to design and build up a system which has integration of elastic and inelastic scattering spectroscopy system. In order to enhance the stability of the system, the standard procedures for calibrating, installing, and operating were designed. The light source of the system can be switched halogen lamp or laser to obtain different spectral information of samples. Furthermore, we can easily change the setting of system to meet our demand in different experiments.
Because the system is limited by the software controlling the rotation angle of the grating; the basic units of spectra is 1 nm, therefore, we scan mercury spectrum condition by erecting elastic scattering spectroscopy. Peak spectral characteristics of full width at half maximum will set at 0.1 nm to erect Raman scattering spectroscopy scanning mercury spectrum condition. In addition to the use of mercury outside resolution spectroscopy system, we further measure the elastic scattering spectrum of commercial gold nanoparticle and the Raman spectrum of aqueous sample (ie. acetone, isopropyl alcohol and water) to verify the feasibility of the system.
