Problems solved by technology

However, there are relatively few studies on the singular photon performance of carbon nanotubes and devices based on the photon performance of carbon nanotubes. In 2002, Science magazine published the research of Ajayan P M et al. (Ajayan P M, Terrones M, Guardia A et al.Science, Nanotubes in a Flash-Ignition and Reconstruction, 2002, 296(26): 705), reported the burning phenomenon of flocculent single-wall carbon nanotubes under the illumination of camera flash lamps, and proposed that there is a gap between single-wall carbon nanotubes and light radiation. Ultra-strong photon-phonon coupling effect leading to photoinduced reconfiguration of single-walled carbon nanotube structures

example 1

[0017] Example 1: The single-walled carbon nanotubes used in this example have a diameter of 1.5nm, a length of 100-300nm, a laser wavelength of 780nm, and a laser energy density of 600-800mW / cm 2 . Figures 2-3 are related experiments based on Example 1. Figure 2 is a cluster of nanobombs, and the paper fibers in the figure are used for positioning. When the laser is focused on the carbon nanotubes, the carbon nanotubes explode. As shown in Figure 3, a shock wave spreading around is formed in the water and blows off a paper fiber.

example 2

[0018] Example 2: The single-walled carbon nanotubes used in this example have a diameter of 2.2nm, a length of 200-400nm, a laser wavelength of 808nm, and a laser energy density of 1000-1200mW / cm 2 . Figures 4-5 are experiments based on Example 2, and Figure 4 is a nanobomb cluster in Example 2. When the laser is focused on the carbon nanotubes, the carbon nanotubes will explode. As shown in Figure 5, the spreading shock wave blasted the surrounding paper fibers.

example 3

[0019] Example 3: A tube bundle or mixture composed of the above two types of carbon nanotubes and carbon tubes of other specifications will explode when triggered by a laser light source containing the above two wavelengths and matching the specifications of other carbon tubes.

Description

1. Technical field [0001] The invention relates to a nanobomb designed based on the singular light quantum properties of carbon nanotubes and near-infrared laser radiation at the micro-nano scale, and belongs to the technical field of nanoscience and quantum optics. 2. Background technology [0002] As a novel nanomaterial, carbon nanotubes have received extensive attention from scientists in various fields in the past ten years. According to the unique mechanical, electrical and magnetic properties of carbon nanotubes, scientists have designed many devices based on carbon nanotubes, such as nanosecond tubes, nanomemory, nanoguns, nanopumps, nanomolecular oscillators, etc. However, there are relatively few studies on the singular photon performance of carbon nanotubes and devices based on the photon performance of carbon nanotubes. In 2002, Science magazine published the research of Ajayan P M et al. (Ajayan P M, Terrones M, Guardia A et al.Science, Nanotubes in a Flash-Ign...
