Method for imaging 1-D nanomaterials

A method for imaging one dimensional nanomaterials comprising steps of:

• S10, providing one dimensional nanomaterials sample, an optical microscope with a liquid immersion objective, a liquid and a prism, wherein the prism comprises a side surface and a top surface, an angle between the side surface and the top surface is less than 90 degrees, and the one dimensional nanomaterials sample is located on the top surface;
• S20, immersing the one dimensional nanomaterials sample in the liquid;
• S30, illuminating the one dimensional nanomaterials sample by an incident beam through the side surface to generate resonance Rayleigh scattering when the carbon nanotube sample is illuminated by the incident beam;
• wherein the incident beam is a white light with a continuous spectrum;
• S40, immersing the liquid immersion objective into the liquid to get a resonance Rayleigh scattering (RRS) image of the one dimensional nanomaterials sample;
• and
• S50, measuring resonance Rayleigh scattering spectra of the one dimensional nanomaterials sample to obtain a chirality of the one dimensional nanomaterials sample.
