摘要
采用简单的共沉淀法(Cpm)成功合成了氮和铬共掺杂硫化镉纳米复合材料(NCps)。为了评估其结构属性,使用 X'pert 高分辨率软件进行了 X 射线衍射(XRD)分析,确认了其复合性质,并确定其粒度在纳米范围内,在 1 至 1.6 纳米之间。能量色散 X 射线光谱(EDX)提供了铬和氮融入 CdS 主基质的有力证据。紫外-可见光漫反射光谱(DRS)分析的一个有趣结果是,由于铬的引入,在带隙中观察到明显的蓝移,同时伴有伯斯坦-莫斯效应,随着氮浓度的增加而导致红移。光致发光(PL)研究中观察到的强烈绿光发射与氮和 Cr2+ 在 F- 中心的捕获有关。此外,振动样品磁力计(VSM)研究揭示了纳米复合材料的独特磁性,尤其是在低磁场下。这些发现揭示了定制带隙和呈现新型磁性能的潜力,为光磁和自旋电子智能设备的应用带来了巨大希望。
Novel Magnetism and Band Gap Tailoring in N-doped CdS:Cr Nanocomposites for Optomagnetic Applications
Nitrogen and chromium co-doped cadmium sulfide nanocomposites (NCps) were successfully synthesized using a simple co-precipitation method (Cpm). To evaluate their structural attributes, X-ray diffraction (XRD) analysis, conducted with X’pert high score plus software, confirmed the composite nature and established their particle size within the nano range, measuring between 1 to 1.6 nm. Further characterization, employing Fourier transform infrared spectroscopy (FTIR) confirms the presence of Cr and N. The energy dispersive X- ray spectroscopy (EDX) provided compelling evidence of the integration of chromium and nitrogen into the CdS host matrix. An interesting outcome of the UV-VIS diffused reflectance spectra (DRS) analysis was the significant blue shift observed in the band gap resulting from the introduction of chromium, accompanied by a Burstein-Moss effect, leading to a red shift as the nitrogen concentration increased. The intense green light emission witnessed in photoluminescence (PL) studies was associated with the trapping of nitrogen and Cr2+ within F- centers. Moreover, vibrating sample magnetometer (VSM) investigations unveiled distinct magnetic behaviors of the nanocomposites, particularly at low magnetic fields. These findings reveal a potential for tailoring band gaps and presenting novel magnetic properties, which could hold substantial promise for applications in optomagnetic and spintronic smart devices.
