Embodiment 1

[0024] Conductive glass (ITO) was ultrasonically cleaned in acetone and ethanol solutions for 15 minutes, and then rinsed with deionized water; 0.02gSb 2 S 3 Add to 10ml 1,2-ethylenediamine and 1ml 1,2-ethanedithiol mixed solvent, stir and dissolve at room temperature to prepare electrodeposition solution; figure 1 As shown, two pieces of conductive glass 2 are used as the working electrode and the counter electrode, and are vertically arranged in the electrolytic cell 1 equipped with the above-mentioned electrodeposition solution 3. The electrode surfaces are parallel to each other, and the cathode constant potential electrodeposition is carried out at a voltage of 4V. The time is 30 minutes. After the electrodeposition is completed, a uniform and dense film is deposited on the conductive glass. The electrodeposited film is heat-treated at 400° C. for 3 minutes under nitrogen gas, and cooled to room temperature to obtain an antimony sulfide film.

Abstract

The invention discloses a preparation method for antimony sulfide films. The method is mainly characterized in that antimony sulfide is added into a mixed solution of 1,2-ethylenediamine and 1,2-ethanedithiol according to the proportion of 0.01-0.03 g of the antimony sulfide to per 11 milliliter of the mixed solution of the 1,2-ethylenediamine and the 1,2-ethanedithiol and is dissolved in the mixed solution, and electro-deposition liquid is obtained; two transparent electrodes are vertically arranged and placed into an electrolytic cell containing the electro-deposition liquid for cathode constant potential electro-deposition, the voltage is 1.5-8 V, the electroplating time is 5-30 min, uniform and compact films are deposited on cathodes after completion of electro-deposition; the electro-deposited films are subjected to heat treatment at 300-400 DEG C under nitrogen atmosphere and are naturally cooled to the room temperature, and the antimony sulfide films are obtained. The preparation method is simple, short in reaction time, high in productivity, suitable for batch production in factories and high in practicability, and the prepared antimony sulfide films can be applied to catalysis and solar cells and has broad application prospects in the field of photoconductive materials.

Description

technical field [0001] The invention relates to a method for preparing an inorganic functional film, in particular to a method for an antimony sulfide film. Background technique [0002] Antimony sulfide is a layered V-VI group direct bandgap semiconductor material with an energy bandgap of 1.5-2.2eV. It belongs to the orthorhombic crystal system and has high photosensitivity and high thermoelectric energy. It is widely used It is also an ideal material for utilizing solar energy in thermoelectric cooling technology, electronic and optoelectronic devices, and optoelectronics research in the infrared region. Currently, for Sb 2 S 3 There have been many researches on the preparation of thin films, and the preparation methods can be classified into the following categories: spray pyrolysis, chemical bath deposition, dipping and thermal evaporation. These preparation methods usually require strict control of experimental conditions, such as high temperature, concentration of m...
