说明

二维材料在量子点中的转变从它们的量子限制效应、表面体积比、溶解度、边缘效应、可调 PL、易于功能化和荧光特性等方面补充了优异的特性。 这些二维量子点要求为二维纳米片赋予新的维度,为了提升到新的水平,需要更好地了解二维量子点的性质、合成方法和应用。 WS2 量子点令人兴奋的光学特性,例如覆盖可见光区域的强激子吸收带、出色的激子荧光、高度可调的 PL、原子级薄结构、分子大小、生物相容性、易于功能化、增强的光稳定性、更高的摩尔消光系数和长 术语光稳定性使它们成为光学传感的有吸引力的候选者。

一般描述

The transformation of 2D materials in QDs form supplement excellent properties from their quantum confinement effects, surface-volume ratio, solubility, edge-effects, tunable PL, ease to functionalize and fluorescence properties. These 2D QDs are demanding to impart new dimension to the 2D nanosheets and in order to advance to next level, the better understanding of the properties, synthesis methods and applications of 2D QDs are needed. The exciting optical properties of the WS2 QDs such as strong excitonic absorption bands covering the visible region, excellent excitonic fluorescence, highly tunable PL, atomically-thin structure, molecular size, biocompatibility, easy functionalization, enhanced photostability, higher molar extinction coefficients and long-term photostability make them attractive candidates for optical sensing.
