Description
Technical field
It is to be related to one kind to detect jewel using Raman spectrum specifically the present invention relates to a kind of discrimination method of jewel
Method, belong to jewel detection technical field.
Background technology
With the progress of jewel synthetic technology and enhancement and treatment, the difference of synthetic gem and natural gemstone is increasingly
Small, identification difficulty is increasing.These jewels are identified with traditional Gemstone Identification instrument, just seem helpless sometimes.Because
The conventional tools such as gemolite, refractometer are that optical property and other physical properties by determining mineral distinguish gem and jade,
Qualitatively qualification result can only be made according to these properties and parameter.Moreover, some its photosensitiveness of different types of jewel and physical property
It is closely similar.
The content of the invention
In view of the above-mentioned problems, simple it is an object of the invention to provide a kind of detection method, what testing result prepared utilizes drawing
The method of graceful spectral unmixing jewel.
The technical scheme that the present invention is provided is such：
A kind of method that utilization Raman spectrum differentiates jewel, it comprises the steps successively：
1) with 400~1200cm-1Wave band Raman spectrum irradiates gemstone surface, detects ligand structure；
2) again with 2800~3100cm-1Wave band Raman spectrum is scanned with the presence or absence of organic pigment and organic coordination group again
CH2、CH3And the organic group of epoxy resin.
Further, a kind of above-mentioned utilization Raman spectrum differentiates the method for jewel, and described Raman spectrum is used
Bruker-R200L type Raman spectrometers, excitation source wavelength is 532nm, sweep time 30s, is superimposed 3 times, using the burnt mould of copolymerization
Formula, laser beam spot diameter is 20 μm, and laser output power is 5m.
Further, a kind of above-mentioned utilization Raman spectrum differentiates the method for jewel, and described jewel is emerald.
Compared with prior art, the technical scheme that the present invention is provided can identify that jewel is deeply detected quick, lossless, exactly
The various optical properties and inherent composition and structure of gem and jade are studied, and detection method is simple.
Embodiment
The present invention is further illustrated below by the mode of embodiment, but does not constitute any limitation of the invention, is appointed
The modification for the limited number of time that who is made in scope of the presently claimed invention is still in scope of the presently claimed invention.
Embodiment 1
1) with 400~1200cm-1Wave band Raman spectrum irradiation jewel emerald surface, detects ligand structure；
2) again with 2800~3100cm-1Wave band Raman spectrum scans jewel with the presence or absence of organic pigment and organic coordination again
Group CH2、CH3And the organic group of epoxy resin.
Above-mentioned Raman spectrum test uses Bruker-R200L type Raman spectrometers, and excitation source wavelength is 532nm, is swept
Time 30s is retouched, is superimposed 3 times, using common focusing mode, laser beam spot diameter is 20 μm, and laser output power is 5m.
Above-mentioned detection is in 200--1200cm-1Region represents jadeite crystal structure Si-O stretching vibration wavelength 1041cm-
1 and bending vibrations wavelength 701cm-1Characteristic peak, and in 2800~3100cm-1Without obvious raman spectra in region, then explanation is
A goods, if in 2800~3100cm-1There is obvious raman spectra in region, illustrating to mix has silica gel, to pass through artificial treatment
B goods.
