Abstract ZnS coating with oleic acid nano-particles have been successfully synthesized through the oil-phase thermal injection method. As-prepared samples are characterized by powder X-ray diffraction, transmission electron microscopy and spectra analysis. The emission color of ZnS NPs changes from blue to cyan with different ratio of Zn/S. ZnS:xEu3+ NPs with different doping concentrations of Eu3+ ions have different emission intensities and CIE coordination. The emission peaks vary with the change of y value of ZnSeyS1-y NPs, and the chromaticity coordinate transit from green to yellow region. The emission color and mechanism of the luminescent properties of ZnS, ZnS:xEu3+ and ZnSeyS1-y NPs are studied in detail. The results indicate that the thermal mixture injection without toxic is an effective and green method for synthesizing metal sulphitde, and the energy level structure, particle size, photoluminescence of ZnS can be achieved by forming different defect or doping of Eu or Se ions.

热注射法对硫化锌纳米粒子的发光调制

摘要 采用油相热注射法成功合成了油酸纳米粒子硫化锌涂层。制备的样品通过粉末 X 射线衍射、透射电子显微镜和光谱分析进行表征。ZnS NPs 的发光颜色从蓝色变为青色，具有不同的 Zn/S 比。具有不同 Eu3+ 离子掺杂浓度的 ZnS:xEu3+ NPs 具有不同的发射强度和 CIE 配位。发射峰随ZnSeyS1-y NPs y 值的变化而变化，色度坐标从绿色区域过渡到黄色区域。详细研究了 ZnS、ZnS:xEu3+ 和 ZnSeyS1-y NPs 的发光颜色和发光特性的机制。
