| titleOfInvention | A kind of preparation method of uncooled lead selenide near-infrared detector |
| abstract | The invention relates to a preparation method of an uncooled lead selenide near-infrared detector, comprising the steps of: preparing PbSe nanomaterials; and preparing a substrate. The beneficial effects of the invention are as follows: using spherical PbSe nanocrystalline particles as raw materials, by heating at a low temperature in a nitrogen atmosphere, an infrared film with uniform thickness and maintaining quantum characteristics is obtained; the optical signal is converted into an electrical signal by means of interdigital electrodes. , the near-infrared detector is prepared; the preparation method of the present invention is convenient, low in cost, convenient in mass production, and the prepared infrared detector has good performance; the n-hexane solution containing PbSe nanomaterial is pipetted to the surface of the quartz plate, and heated at low temperature. Then placed in 1,2-ethanedithiol solution; the method of low temperature heating can ensure that the nanomaterial maintains quantum properties and can be evenly distributed on the surface of the quartz plate; also set up interdigital electrodes on the PbSe nanomaterials, interdigitated electrodes It can increase the signal-to-noise ratio of the PbSe near-infrared detector to a certain extent and improve the detection rate of the signal. |
