Embodiment 1

[0049] Morpho butterfly wings have a brilliant structural color, which is caused by its fine three-dimensional micro-nano structure. like figure 2 (a) Paste the original butterfly wings on the bottom of the container, the bottom material of the container is calcium fluoride, water vapor flows through the top of the butterfly wings and is adsorbed on the surface of the micro-nano structure of the butterfly wings. The external infrared signal is irradiated to the back of the butterfly wing through the bottom of the container. Due to the interaction between the external infrared signal and the adsorbed water molecules, the temperature of the water molecules is raised and desorbed from the surface of the butterfly wing, so that the reflection spectrum of the butterfly wing changes, so that the The invisible infrared signal is converted into a visible light signal, and the ultraviolet-visible spectrometer is used to observe the change of the reflection spectrum of the butterfly wi...

Abstract

The invention relates to a method for achieving infrared detection by a desorption phenomenon of infrared excitation molecules. The method comprises the following steps that micro-nanometer structure surfaces absorb chemical molecules; infrared signals are added to the micro-nanometer structure surface, and the chemical molecules adsorbed by the micro-nanometer structure surface are desorbed from the micro-nanometer structure surfaces under excitation of the infrared signals; micro-nanometer structures has changes of physical properties due to the molecular desorption, and the changes of the physical properties of the micro-nanometer structures are detected through a device, and therefore detection of the extra infrared signals is achieved. Due to an effect of the extra infrared signals, the chemical molecules adsorbed on the micro-nanometer structure surfaces are desorbed from the micro-nanometer structure surfaces because the chemical molecules absorb the infrared signals to make the temperature rise, the optical property, electrical property, magnetic property and other physical properties of the micro-nanometer structures is caused to change, and therefore the phenomenon is utilized to achieve the detection of the infrared signals. Compared with existing infrared detection technologies, the method for achieving the infrared detection by the desorption phenomenon of the infrared excitation molecules has the advantages that the sensitivity is high and feedback signals are easy to analyze and the like.

Description

technical field [0001] The invention belongs to the field of sensing and detection, and in particular relates to a method for realizing infrared detection by utilizing the desorption phenomenon of infrared excitation molecules from the surface of micro-nano structures. Background technique [0002] Infrared rays are electromagnetic waves with wavelengths between visible light and microwaves. All objects with a temperature above absolute zero emit infrared light. Due to the non-destructiveness of infrared detection technology and the unique information it reveals, it determines the importance of this technology in the supervision of industrial production processes, medical diagnosis and military and widely used. [0003] Infrared detection technology is generally divided into two types: cooled and uncooled infrared detection technology. Cooled infrared detection is generally based on photoelectric and photovoltaic technologies, but requires additional cooling, so its price ...
