Introducing room – temperature ferromagnetism, in wide bandgap semiconductors has gained significant interest in the field of diluted magnetic semiconductors. Here, the Cadmium Sulfide and CdS – C. odorata leaf extract composites, fabricated through green synthesis routes, show room – temperature ferromagnetism and improved electrical conductivity. Here, the origin of magnetism is attributed to the trapped electrons in the F – center, which is emanated from the sulfur vacancies. Besides, the composite has ligand – induced magnetism due to the electron transfer at the interface between the CdS and the leaf extract. Enhanced conductivity observed in the composite nanoparticle is due to the loss of a few electrons from the F – center to the conduction band. The leaf extract modified CdS samples exhibit unconventional ferromagnetism which makes them ideal for spintronics applications without any magnetic impurity doping. The improved electrical conductivity exhibited by the samples forecast their multi – utility potential to be exploited for electrical and photovoltaic applications in addition to their DMS and spintronic applications.

在宽带隙半导体中引入室温铁磁性已经在稀磁半导体领域引起了极大的兴趣。在这里，硫化镉和CdS –香茅通过绿色合成路线制造的叶片提取物复合材料具有室温铁磁性和改善的导电性。在这里，磁性的起源是由于F-中心的电子被捕获，这是由硫空位产生的。此外，由于电子在CdS和叶片提取物之间的界面处转移，该复合材料具有配体感应磁场。在复合纳米粒子中观察到的导电性增强是由于从F-中心到导带的一些电子的损失。叶提取物修饰的CdS样品表现出非常规的铁磁性，这使其非常适合自旋电子学应用，而无需掺杂任何磁性杂质。
