The metal Nano structure of high-sequential is prepared, although which obviating the internal oxidation problem of granule, between construction unit
It is distant, cause electric-field enhancing unobvious, corresponding Raman focus is also just very rare；The also method system of nano impression
For equally orderly nanostructured, but construction unit size is equally faced greatly with photoetching process, Raman focus is few, and equipment is held high
It is expensive, the harsh problem of experiment condition, referring to：Tao Ding and Daniel O.Sigle,ACS
Appl.Mater.Interfaces 2014,6,17358-17363.As the preparation method of this traditional aluminum nanostructured, example
Such as photoetching, nano impression, molecular beam epitaxy etc., are subjected to the restriction of the conditions such as apparatus expensive, experiment condition harshness, so as to limit
The extensive application of LSPR is made.
In this numerous synthetic method, it is that a kind of simple, quick, low cost is prepared and received that laser directly inscribes method (LDW)
The method of rice structure.Millisecond laser ablation aluminum is adopted under the assosting effect of electric displacement platform by the restriction effect that rapidly cools down of liquid nitrogen
Target, quickly prepares on the surface of aluminum target and is smaller in size than 100nm aluminum clusters arrays, and which has in UV light region and significantly absorbs.This
The nanostructured meeting surface for planting surface dense distribution goes out preferable SERS performances and highdensity Raman focus, and either strengthens

Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is elaborated.
The sand paper of the pure aluminum target sand for surface paper different model of 20 × 20 × 3mm (first with coarse sandpaper, then is used into fine sand now
Paper) surface of target is sufficiently polished, effectively to remove the oxide layer on surface, carry out in the alumina powder with 50nm
Polishing, with reach surface try one's best flat smooth purpose.Finally the target after polishing is placed in big centrifuge tube carry out it is repeatedly many
Secondary ultrasound, reaches the purpose of crystallization with the soil for removing surface, and in order to be effectively prevented from the oxidation of target material surface, ultrasound is adopted
Be chromatographically pure ethanol solution.
After ultrasound, the aluminum target that purity is 99.995%, thickness 3mm is placed in the beaker equipped with liquid nitrogen, while by beaker
It is placed in thermos cup to ensure that liquid nitrogen environment is stablized in beaker, prevents the violent boiling of liquid nitrogen.Using millisecond pulse Nd:YAG
Laser (fundamental frequency 1064nm) focuses on photoirradiation target surface, and laser energy is 2.227J, repetition rate 1Hz.By the auxiliary of electric displacement platform
Effect is practiced shooting.Specific experimental provision is as shown in Figure 1.
Before the patterning of nanostructured is realized, the nanostructured for first having to determine obtained by us be dense distribution in
Inside laser action point, so we observe the nanostructured of diverse location inside laser action point simultaneously, such as Fig. 2 institutes
Show.A () is the low power scanning of laser action point, (b) centered on position scanning, (c), (d) figure off center position progressively.
It can be seen that nanostructured does not have too big change in the size and pattern of the diverse location of laser action point, being completely can be with
It is the preparation of first large area, highdensity aluminum nanostructured by the assosting effect of electric displacement platform.
For vivider specific observation, Fig. 3 shows that the target material surface pattern obtained under the assosting effect of electric displacement platform is
By the preiodic type structure for necessarily rising and falling, there is groove, the corresponding center for being to focus on light in this structure.In order to prove us
Without being oxidized in laser action process, Fig. 4 (c), (d) sets forth the x of aluminum nanostructured to the aluminum nanostructured of preparation
X ray diffration pattern x and high resolution transmission electron microscope picture.Do not see in Fig. 4 (c) that the diffraction maximum of aluminium oxide illustrates me
Product be aluminum, the high power transmission electron micrograph of Fig. 4 (d) points out that laser action product is that the aluminum containing oxide layer is received
The nucleocapsid structure of rice grain, the surface of aluminum nanoparticles is amorphous oxide layer, and thickness is in 2.5nm or so.
Further we also explore the impact of the liquid level for Raman spectrum of liquid nitrogen.Obtain on height too high target surface
Obtaining effective laser energy reduces, and target can not be by effectively ablation, and the ablated phenomenon of the too low target material surface of liquid level is serious,
Both of these case can all cause the reduction of nanostructured, Raman hydraulic performance decline.Fig. 5 mainly discusses liquid level for 1-2.5cm
Optimum capacity scope, either from pattern, absorb or Raman spectrum, can draw their performance be all it is consistent,
1-2.5cm is optimal liquid level scope.A () figure is the absorption picture under different liquid levels, its Raman figure with (b) figure
And the shape appearance figure of (c) (d) (e) all shows, these three liquid levels are optimum liquid levels, and its Raman performance is consistent
's.
In Raman test process, material is had significant effect for performance in the state of target material surface, if there is water on surface
Mobility then fluorescence signal is too strong；Dry tack free, Raman signal are also bad, so will ensure target material surface half in test process
The wet half-dried state for not having liquid flowing carries out Raman test.
Although above in conjunction with accompanying drawing, invention has been described, the invention is not limited in above-mentioned being embodied as
Mode, above-mentioned specific embodiment is only schematic, is not restricted, and one of ordinary skill in the art is at this
Under the enlightenment of invention, in the case of without departing from present inventive concept and scope of the claimed protection, many shapes can also be made
Formula, these are belonged within protection scope of the present invention.
