Embodiment 1

[0012] Example 1. SnS with PP substrate 2 Fabrication of Nanopaper Self-Assembled Microsphere Thin Film Flexible Photodetection Devices

[0013] A. Add 1.7525g SnCl 4 ·5H 2 O(CP), 1.609g thioacetamide (TAA) and 40mL ethanol were placed in a 100mL beaker and stirred for 30 minutes, then transferred to a 50mL stainless steel reaction vessel with polytetrafluoroethylene and sealed. After 24 hours of constant temperature at 180°C, centrifuge, wash with ethanol and pure water three times alternately and centrifuge, dry at 60°C for 3 hours, and collect the product. The structure is confirmed by XRD, and the appearance is as follows: figure 2 (a) and 2(b)

[0014] B. Select a PP flexible substrate with a size of 0.5cm×2cm×0.2mm and paste a 0.5cm×1cm double-sided tape on one side, then mix ethanol with the SnS prepared above 2 The microsphere suspension was evenly coated on the double-sided adhesive tape and dried naturally. Then, in SnS 2 Two enamelled copper wires with a diam...

Abstract

Discloses are a tin sulfide nano paper self-assembly microsphere production method and an optical detector of a microsphere film. A tin sulfide nano paper microsphere is produced by an ethanol solvent hot method, the tin sulfide nano paper microsphere and ethanol suspension liquid is arranged on a flexible substrate such as PP (Polypropylene), PET (Polyethylene Terephthalate) and paper in a dropwise-added or coating mode, the flexible substrate is pasted through a double sided tape, the film is formed through natural drying, a simple metal wire and a paper frame mask cover the film, three conductive electrodes such as titanium and gold or gold are sputtered through vacuum ions, the independent electrodes are reserved on the tin sulfide nano paper microsphere film after the mask is uncovered, and accordingly the simple optical detector from ultraviolet 300 nm to near infrared 830 nm is formed. The performance is good and reliable according to experimental results. The invention also discloses materials of the tin sulfide nano paper self-assembly microsphere and a machining method of the detector.

Description

technical field [0001] The present invention relates to SnS 2 Synthesis of nanopaper self-assembled microspheres and fabrication of their microsphere films for flexible photodetectors. Specifically, large-scale synthesis of SnS by ethanol solvothermal method 2 Nano paper self-assembled microspheres, then select a transparent and flexible polypropylene (PP) film of appropriate size and paste double-sided tape on this side, and then mix ethanol (or water or a volatile organic solvent that is harmless to the tape and water) organic solvent mixture) and SnS 2 The microsphere suspension was coated onto double-sided tape. Then pass through a simple mask and vacuum-evaporate metal electrodes, and remove the mask so that only SnS not covered by metal is left between the two electrodes. 2 microsphere membrane. Background technique [0002] Self-assembled nanomaterials have both the quantum size effect of nanomaterials and the material operability of macroscopic materials, which ...
