Nano multi-layer structure enhanced fluid substance detection method

摘要: The invention relates to a nano multi-layer structure enhanced fluid substance detection method. An existing method is weak in Raman signal, low sensitivity and high requirements on detected material. According the method, based principle, peak structural layer arranged part; furthermore, metal inert material surface of layer; passes through area subjected laser scattering; information by spectrometer detector; matter characteristic realized spectrum analysis. disclosed has characteristics being signal-to-noise ratio, varied morphology fluid, wide application range, like, system easy construct, functions are extend.
