| 제목 | Study on optical properties of copper sulfide nanoparticles synthesized by a solvothermal method |
| 초록 | In the study, copper sulfide (CuxS) nanoparticles, electric conductors, have been synthesized by a solvothermal reaction of copper sulfate pentahydrate (CuSO4·5H2O) and sodium sulfide pentagydrate (Na2S·5H2O) in aqueous solutions. The molar ratio of Cu/S was controlled by parameters such as reaction time, temperature, and pH since that affected optical properties of copper sulfide. The reaction temperature was optimized at 95℃ through the experiments from room temperature to near 100℃. The effects of pH and reaction time were performed from 2 to 13 and from 0.5 h to 2 h, respectively. The samples are conducted optical properties by X-ray diffraction (XRD), emission scanning electron microscopy (FESEM), energy dispersive X-ray spectrometer (EDS), and UV-visible spectrometer. The nanoparticles obtained from the study can be applied for the window film with a high light transmittance and UV-cutting. |
