Nanoinks composed of quantum dots (QDs) are applied in light-receiving devices and light-emitting devices such as solar cells and displays. However, since the most widely used QDs, PbS and CdS, are toxic and environmentally concerning, alternative materials need to be developed. We synthesized and analyzed Ag chalcogenide nanoparticles, including AgBiS and AgS nanoparticles, which are eco-friendly materials. AgBiS and AgS QD films were prepared by spin-coating nanoparticle solutions and subsequent heat treatment. The effects of the heat treatment on residual ligands and photoluminescence were determined by surface analysis. The photocurrent response of the AgBiS and AgS QD films was measured in the near-infrared region, and the effect of the heat treatment temperature was investigated. The results indicate that AgBiS and AgS are prospective materials for near-infrared photodetectors.
由量子点（QD）组成的纳米墨水被应用于诸如太阳能电池和显示器等光接收器件和发光器件中。然而，由于使用最广泛的量子点硫化铅（PbS）和硫化镉（CdS）具有毒性且对环境有害，因此需要开发替代材料。我们合成并分析了包括硫银铋（AgBiS）和硫化银（AgS）纳米颗粒在内的硫属银化物纳米颗粒，它们都是环保材料。通过旋涂纳米颗粒溶液并随后进行热处理来制备硫银铋和硫化银量子点薄膜。通过表面分析确定热处理对残留配体和光致发光的影响。在近红外区域测量了硫银铋和硫化银量子点薄膜的光电流响应，并研究了热处理温度的影响。结果表明，硫银铋和硫化银是用于近红外光电探测器的有前景的材料。
