Abstract

The invention discloses a composite solid-solution semiconductor-coupled carbon-based nanoparticle film with an anti-reflection micro-nano structure and a preparation method thereof. The method includes selection, pretreatment and activation treatment of butterfly wings, and chemical deposition on the butterfly wings Metal / semiconductor coupled nanoparticles, vacuum carbonized butterfly wings and other steps. The method for preparing a composite solid-solution semiconductor-coupled carbon-based nanoparticle film with an anti-reflection micro-nano structure uses butterfly wings to make a composite solid-solution semiconductor nanoparticle film, and the manufacturing process is simple, safe, stable, low in cost, and energy-consuming. Low, the prepared nanoparticle film has achieved a macroscopic large-scale, and has a butterfly-wing anti-reflection microstructure. This film has high absorption and anti-reflection performance in the infrared spectrum band, and has excellent infrared photothermal conversion performance and photoelectric effect, thereby realizing infrared heat-assisted infrared detection, which can be applied to infrared photoelectricity and infrared detection.

Description

technical field [0001] The invention relates to the field of metal and semiconductor nanoparticle films, in particular to a composite solid-solution semiconductor-coupled carbon-based nanoparticle film with an antireflection micro-nano structure and a preparation method. Background technique [0002] Infrared sensing is an important technology that is widely used in energy, environmental science, medical engineering and public safety, such as energy metering, environmental pollution monitoring, remote control, thermal imaging, night vision, thermal photoelectricity, medical imaging, Optical communication, fire detection, monitoring, industrial process control, analysis and detection, etc. Most infrared detection can be divided into three categories: bolometric, pyroelectric and photoelectric infrared detection. [0003] Previously, most of the infrared sensing devices that could meet the requirements of practical applications were cooled infrared sensors. However, due to t...
