Spectrographs for analyzing nanomaterials

Abstract

The optical schemes of high numerical aperture spectrographs based on concave holographic diffraction gratings are described. A calculations of an optical schemes using flat field spectrograph method for analyzing the fluorescence of all kinds of Quantum dots in a wide range of wavelengths with spectral resolution of 6,3 nm are submitted. A special calculation of spectrographs for investigating CdSe/ZnS, InP Quantum dots with high resolution of 1 nm are given because of their wide uses. An experimental mounting for analyzing Raman scattering in carbon nanotubes is described. Experimental results are given. On the basis of these results the requirements for optical characteristics of a compact specialized spectrograph for analyzing Raman scattering in carbon nanotubes are developed. The calculation of an optical scheme using flat field spectrograph method with spectral resolution of 3.5 cm-1 is submitted.
