摘要

利用连续离子沉积法和水热法在FTO基底上制备了Ag⁺掺杂Bi₂S₃薄膜(Ag-Bi₂S₃),探究了Ag⁺浓度对Bi₂S₃薄膜光电性能的影响。并用扫描电镜、能谱、X射线衍射(XRD)、紫外-可见分光光度计(UV-Vis DRS)等手段对其进行表征。结果表明:Ag-Bi₂S₃薄膜局部出现由较短的条状晶体聚集形成的花辫带,并有Ag元素的能谱峰,Ag⁺掺杂进Bi₂S₃薄膜;在Ag-Bi₂S₃的XRD衍射峰中出现AgBiS₂相的衍射峰,表明Ag元素在Ag-Bi₂S₃薄膜中的存在形式为AgBiS₂;UV-Vis DRS测试结果显示Bi₂S₃薄膜和Ag-Bi₂S₃薄膜的禁带宽度分别为1.65eV和1.47eV;Ag-Bi₂S₃薄膜的光电压和光电流分别为0.2013V和0.059mA/cm²,比Bi₂S₃薄膜的光电压和光电流分别提高了30.6%与168.1%;Ag-Bi₂S₃的载流子浓度4.83×10¹⁴cm^-3,比Bi₂S₃的8.17×10¹²cm^-3提升了两个数量级。

Abstract

The Ag⁺ doped Bi₂S₃ film (Ag-Bi₂S₃) was prepared on the FTO substrate by continuous ion deposition method and hydrothermal method.The influence of Ag⁺ doping concentration on the photoelectric performance of Bi₂S₃ film was explored.it was characterized by SEM,EDS,XRD,UV-Vis and other means.The results shown that in the SEM image of the Ag-Bi₂S₃ thin film,there were locally flower braids belt by the aggregation of shorter strip crystals,and the peak of Ag element appeared in the EDS spectrum,indicating that Ag⁺ was successfully doped into the Bi₂S₃ thin film.AgBiS₂ diffraction peaks for XRD appeared in the Ag-Bi₂S₃ phase diffraction peaks,indicating that the Ag element in the Ag-Bi₂S₃ film was AgBiS₂.The UV-Vis DRS test results shown that the band gaps of the Bi₂S₃ film and the Ag-Bi₂S₃ film were 1.65eV and 1.47eV,respectively.The photovoltage and photocurrent of the Ag-Bi₂S₃ film were 0.2013V and 0.059mA/cm²,respectively,which were 30.6% and 168.1% higher than those of the Bi₂S₃ film.The carrier concentration of Ag-Bi₂S₃ was 4.83×10¹⁴ cm^-3,which was two orders of magnitude higher than the 8.17×10¹²cm^-3 of Bi₂S₃.
