Özet
Co-alloyed ZnS quantum dots were synthesized with the coprecipitation technique at 300 K. The measurements of current density versus voltage and incident photon to electron-conversion efficiency showed that Co-alloyed ZnS quantum dots could be utilized as the materials to boost the performance of devices. Furthermore, the magnetic, optical and structural characteristics of Co-alloyed ZnS quantum dots were investigated. It was determined that Co-alloyed ZnS quantum dots have a cubic structure and their size is 2.71 nm, which is smaller than the size of pure ZnS quantum dots (2.72 nm). Optical studies revealed that the absorption and emission of Co-alloyed ZnS quantum dots are blue shifted compared to pure ZnS quantum dots. The magnetization versus magnetic field measurement indicated that Co-alloyed ZnS quantum dots show ferromagnetic behavior at 300 K. As a conclusion, this study proposes that Co-alloyed ZnS quantum dots could be convenient for optical and magnetic applications.
