Time being illuminated at situation about not disturbed by other factors only diamond, by observe diamond material produce displacement peak position, can
To judge that diamond is naturally occurring or synthetic.This utility model is by observing the luminescence generated by light spectral line natural, synthesis spy to diamond
Levy and judge, such as, study rough diamond, CVD synthesizing diamond, HTHP synthesizing diamond.Synthesizing diamond different from rough diamond it
Place is that synthesizing diamond shows the lattice defect being different from rough diamond.These different lattice defects are that diamond is in growth course
In all absorption impurity compositions cause, but these impurity exist with mode in different proportions so that they have different spectrum
Characteristic.Using this utility model, it may be determined that whether be naturally occurring or synthetic for diamond, this device is portable, and
Its cost uses with being dimensioned for small-sized Gem Studies laboratory, jewelry whole seller and large-scale jewelry retail division.Although laser is such as
Really eyes can have been injured by leakage, but complete isolation cover can provide protection.
The laser of wavelength 405nm can occur strong interaction to make sample luminous, therefore with various types of diamonds
Method and apparatus of the present utility model is applicable to the test of any type diamond.The lattice defect degree of different types of diamond is not
With.If being difficult to by observing diamond peak position feature, then be proposed with chiller and under cryogenic diamond surveyed
Examination.
Judging of rough diamond: when spectral position be positioned at 415nm and then can conclude that at 741nm diamond as rough diamond,
As in Figure 2-4；
The judgement of CVD synthesizing diamond: if there is 737nm peak position, without 415nm peak position, can conclude that diamond is that chemical gaseous phase is sunk
Shallow lake method (CVD) synthesizing diamond, as shown in Figure 5；
The judgement of HTHP synthesizing diamond: if there is the peak position of 883nm and 884nm, this peak position is relevant to Ni, Fe, Co, can sentence
Determining diamond is High Temperature High Pressure (HTHP) synthesizing diamond, 883nm and 884nm is closely located to would generally be combined together, as shown in Figure 6.
Having 427 nm peak positions from these figures of Fig. 2-Fig. 6,427nm is the peak position that a diamond is intrinsic, for getting
Bright getting on diamond, diamond sample whatever has this peak.
The method observing photoluminescence spectra feature has a following two:
1) test under room temperature
Under normal room temperature condition, diamond sample is tested, observe photoluminescence spectra feature, if diamond is former
Shi Ze needs to be cleaned diamond, finds relatively flat position.
2) low-temperature test
In cooling assembling device, pour the cooling liquids such as liquid nitrogen into, sample is placed in chiller upper glass plate sample
Test.
Under all situations, the intensity of radiating light source must arrive by force and be enough to obtain observable Spectral Phenomenon.
To further describe this utility model with example and enclose relevant drawings below, accompanying drawing comprises: Fig. 2 and 3 is synthesis
The spectrogram of diamond, is by using the method and apparatus of this utility model to obtain.
Only several specific embodiments of the present utility model disclosed above, but this utility model is not limited to this,
The changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
