Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard was proposed by the Chinese Academy of Sciences.
This standard is under the jurisdiction of the National Nanotechnology Standardization Technical Committee (SAC/TC279).
This standard was drafted. National Nanoscience Center.
The main drafters of this standard. Guo Yanjun, Wang Hanfu, Xu Bo, Bai Lu.
introduction
The application of Raman spectroscopy in nanomaterial characterization is becoming more and more extensive [1, 2]. Raman shift calibration is an important part of Raman analysis. Pulling
In the daily operation of the Man spectrometer, especially in the detection of nanomaterials requiring high energy resolution, the Raman frequency shift is frequently checked or performed.
Calibration. At present, the most commonly used reference source for absolute wavenumbers is the emission spectrum of low-voltage atomic line lamps (such as low-pressure mercury lamps, argon lamps, xenon lamps, etc.).
Line [3-6]. This standard will be developed to measure and calculate the frequency shift correction value for the calibration of Raman spectrometers using standard low-voltage atomic line lamps.
For technical support.
Nanotechnology for Raman spectroscopy calibration
Frequency shift correction value
1 Scope
This standard specifies calibration conditions and calibration methods for frequency shift correction values for Raman spectral calibration.
This standard applies to the daily use of a dispersion-type Raman spectrometer with a single-stage, two-stage or three-level grating with a continuous laser as the excitation source.

3 Terms and definitions
The following terms and definitions defined in GB/T 13966 and JJF 1544 apply to this document.
3.1
Low-voltage atomic line lamp low-pressureatomemissionlamp
Low-pressure gas discharge source.
Example. xenon lamp, argon lamp or mercury lamp.
3.2
Static spectral window staticspectralwindow
The spectral range obtained by the spectrometer when the grating of the spectrometer is in static mode, ie when the grating is stationary at a specified angle.
Note. The static spectral window is usually obtained by specifying the center wave number in the case of charge coupled device (CCD) detection. The starting wave number and the cutoff wave number range are determined by
The physical structure of the spectrometer itself is defined.
3.3
Rayleigh Line Rayleighline
The same frequency as the incident laser.
Note. The composition includes all photons whose energy does not change, such as Rayleigh scattering, diffuse scattering, and surface reflection generated by laser irradiation.
4 Overview
The Raman spectrum is a spectrum obtained by changing the frequency of monochromatic light by inelastic scattering of atoms in a molecule or a lattice. Raman spectrum package
Information containing molecular or lattice vibrations has a wide range of applications in the fields of material identification, crystal structure analysis, and stress analysis. Dispersive Raman Light
The spectrometer usually uses a laser as a light source and can be equipped with one or more wavelengths of lasers; the grating is the main dispersion component, which can have a single stage, two
Grade or tertiary grating. The accuracy of the physical structure of the spectrometer and the mechanical repeatability of the control motor can measure the accuracy of the Raman shift.
