摘要:
为制备高品质、性质稳定的硫化锌量子点,采用硫代乙酰胺在水热条件下的均相沉淀法制备了硫化锌量子点,并采用X射线衍射、透射电子显微镜和荧光光谱仪分别表征了所制得量子点的物相、颗粒尺寸和发光性质,考察了反应时间对量子点物相、颗粒尺寸和发光性质的影响.结果表明,在80 ℃水浴条件下,可以获得颗粒尺寸在20 nm以下,面心立方结构的硫化锌量子点.发光性能测试表明:制备的硫化锌量子点可被330 nm紫外光有效激发,产生位于430 nm附近的蓝光发射;随着反应时间的延长,量子点颗粒尺寸增大、发光性质减弱.
Abstract:
To make high quality and stable property zinc sulfide quantum dots, we focused on a homogeneous precipitation method utilizing thioacetamide hydrolysis reaction under a hydrothermal conditions to prepare zinc sulfide quantum dots. The crystal phases, particle size and luminescent properties were respectively characterized by X-ray diffraction, transmission electron microscopy and fluorescence spectrometer. The effects of the reaction time on the crystal phases, particle size and luminescent properties were also investigated. Results show that the face-centered cubic zinc sulfide quantum dots with particle sizes smaller than 20 nm are obtained by hydrothermal homogeneous at 80 ℃. Luminescent properties tests show that the quantum dots excited by 330 nm present blue emission at about 430 nm; and the luminescent intensity decreases with the increasing reaction time and the particle sizes increasing.
