  • 近年来, 由于独特的电子结构及优异的光电特性, 过渡金属硫族化合物(TMDs)吸引了研究者的广泛关注. 本文采用“自上而下”的超声剥离法成功制备了尺寸约为3.1 nm的六方结构单分散1T相二硫化锆量子点(1T-ZrS2 QDs). 采用紫外-可见吸光度及光致发光方法, 系统研究了1T-ZrS2 QDs的光学特性. 研究发现: 1T-ZrS2 QDs在283 nm和336 nm处存在特征吸收峰, 并且斯托克斯(Stokes)位移了约130 nm, 荧光量子产率高达53.3%. 研究结果表明: 1T-ZrS2 QDs具有优良的荧光性能及独特的光学性质, 使其在光电探测、多色发光等器件中有潜在的重要应用价值.
    In recent years, transition metal chalcogenides (TMDs) have attracted extensive attention of researchers due to their unique electronic structure and excellent photoelectric properties. In this paper, hexagonal structure 1T-ZrS2 quantum dots (QDs) having a monodisperse grain size of around 3.1 nm is prepared by the ultrasonic exfoliation method. The preparation includes the following steps: ZrS2 powder is ground, followed by ultrasonic exfoliation in 1-methyl-2-pyrrolidone (NMP), and 1T-ZrS2 QDs are collected after centrifugation. The structure, morphology and optical properties of the QDs are studied in detail. The structure, morphology, size distribution, and elemental composition of 1T-ZrS2 QDs are studied by using X-ray diffractometer (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The chemical bonds of 1T-ZrS2 QDs are characterized by X-ray photoelectron microscopy (XPS) and Fourier transform infrared spectrometer (FTIR). The TEM and AFM results show that the 1T-ZrS2 QDs are spherical in shape with uniform size distribution. The sizes of the 1T-ZrS2 QDs follow a Gaussian fitted distribution with an average diameter of WC = 3.1 nm and the FWHM is 1.3 nm. The XRD diffraction pattern of 1T-ZrS2 QDs show wide dispersed diffraction peaks, which is the characteristic of QDs. The diffraction peak at 2θ = 32.3° (d = 0.278 nm) corresponds to the (101) crystal plane, and the weak diffraction peak at 2θ = 56.8°(d = 0.167 nm) belongs to the (103) crystal plane. The grain size is also calculated by using the Debye-Scherrer formula, and the calculated value (2.9 nm) is consistent with the result of TEM (3.1 nm). Two Raman vibration modes (E1g and A1g) are observed. The E1g (507.3 cm–1) and A1g (520.1 cm–1) modes relate to the in-plane and out-of-plane vibration respectively. The Raman intensity of the A1g vibration mode is stronger than that of E1g. The UV-Vis and photoluminescence (PL and PLE) characterizations exhibit that the 1T-ZrS2 QDs have two UV absorption peaks at 283 nm and 336 nm, respectively. The Stokes shift is ~130 nm, the fluorescence quantum yield reaches up to 53.3%. The results show that the 1T-ZrS2 QDs have the excellent fluorescence performance and unique optical properties, which make the 1T-ZrS2 QDs an important material for developing photodetectors, multi-color luminescent devices, and other devices.
