Description
Technical field
The utility model relates to the Raman spectrum detection technique, especially a kind of Raman signal intensifier that is used with the Raman detection probe.
Background technology
The Raman spectrum detection technique uses laser to obtain the spectral information of material molecule aspect, has powerful ability at harmless Physical Property Analysis and discriminating.Raman spectrum detects the fields such as food security, drug inspection, drugs detecting, judicial expertise, gemstone testing and environment measuring that have been widely used in.In actual use, because Raman signal is very faint, need utilize Surface enhanced raman spectroscopy technology (SERS) that Raman signal is strengthened, so that spectrometer detects it.The Surface enhanced raman spectroscopy Technology Need contacts testing sample with the metal particle of nanoscale, concrete operation method is the roughened metal surface that sample is positioned over nanoscale, or in sample solution, drip the enhancing reagent that contains metallic nano-particle, with laser sample is shone again, with the Raman signal that has been enhanced.
Traditional Raman probe only has the function that laser is exposed to sample and receive the Raman diffused light that sample sends, and does not have the function that strengthens Raman signal.Occurred some novel probe designs in recent years, made it have the function that strengthens Raman signal.CN101713738A makes taper with the shape of detection fiber as the invention patent mandate notification number, and in most advanced and sophisticated welding a quartzy microballoon, metallic nano-particle on the surface-coated of conical fiber and quartzy microballoon forms and to have the probe that Raman strengthens function; Utility model Granted publication CN202442964U then will directly be structured at the bottom of the active group of Surface enhanced raman spectroscopy on the end face of detection probe optical fiber, forms to have the probe that Raman strengthens function.Yet these designs all need itself to transform again popping one's head in, and the former technology is complicated, and cost is higher, and the latter can only produce Raman signal in the end face limited area and strengthen, and it is limited that the Raman of realizing strengthens effect, all is unfavorable for practicality.At this, a kind of Raman signal intensifier that we propose can use with traditional Raman probe incorporated, reduces cost, and can obtain the effect of Raman enhancing preferably.
The utility model content
The purpose of this utility model provides the Raman signal intensifier that a kind of and Raman detection probe is used, and is not only simple in structure, and can be used realization with traditional Raman detection probe and strengthen effect preferably.
The utility model purpose is achieved through the following technical solutions: a kind of Raman signal intensifier that is used with the Raman detection probe, comprise a support that is connected with the Raman probe, export laser and receive Raman diffused light by the Raman probe, wherein: the cambered surface reflecting plate that scribbles the metallic nano-particle layer is set on the described support, and the metallic nano-particle layer is located on the concave surface of cambered surface reflecting plate.The utility model is not only simple in structure, realizes easily, and can be used with traditional Raman detection probe, realizes that Raman signal strengthens effect preferably, can be used for solid, and the Raman spectrum of liquid or gaseous sample detects.
On the such scheme basis, described metallic nano-particle layer is popped one's head in over against Raman.
On the such scheme basis, described support is the extension of cambered surface reflecting plate, goes up and regulate the distance of metallic nano-particle layer between popping one's head in Raman by being bolted to Raman probe.
The utility model principle is: the laser of exporting by popping one's head in also receives Raman diffused light.
Metallic nano-particle is coated in the concave surface of cambered surface reflecting plate by the method for self assembly, the sample that contacts with metallic nano-particle produces the Surface enhanced raman spectroscopy phenomenon under the laser irradiation, the curved surfaces of reflecting plate has reflection on the one hand and focuses on the function of Raman diffused light, Raman diffused light is converged to probe, increase the Raman signal intensity that probe receives; Curved surfaces can make the zone of laser between reflecting plate and probe of sending of popping one's head in come back reflective on the other hand, increases the effect probability of laser and sample, thereby produces more Raman signal.The holder part that is connected with probe can be regulated, to change the distance between reflecting plate and the probe.Can be by changing this apart from realizing maximum Raman signal intensity when reality is used.
Superiority of the present utility model is: simple in structure, and can be used with traditional Raman detection probe, and not need itself to transform popping one's head in by the technology of complexity, cost is lower; And by to the effect of converging of Raman signal with make laser come back reflective in certain zone, making probe receive stronger Raman signal, improve the detection efficiency of Raman probe, thereby realize the Raman spectrum of micro-example is detected.The Raman Enhancement Method that strengthens reagent is used in contrast, and the utility model can be reused in different occasions, thereby has reduced use cost.
