Abstract Facile single pot hydrothermal approach has been used to synthesize water-dispersible fluorescent molybdenum disulfide (MoS2) quantum dots (QDs) capped with 1,4-diaminobutane (DAB). The developed MoS2 QDs were investigated with different techniques and further used for selective sensing of the explosive 2,4,6-trinitrophenol (TNP) up to a limit of detection of 5 μ M . The PL intensity of QDs is quenched in the presence of TNP following the radiative energy transfer mechanism.

基于胶体二硫化钼量子点的光学传感器用于检测水性介质中的 2,4,6-TNP 炸药

摘要 简便的单锅水热法已被用于合成水分散性荧光二硫化钼 (MoS2) 量子点 (QDs)，并以 1,4-二氨基丁烷 (DAB) 封端。使用不同的技术研究了开发的 MoS2 QD，并进一步用于选择性检测爆炸物 2,4,6-三硝基苯酚 (TNP)，检测限为 5 μM。根据辐射能量转移机制，在 TNP 存在下，QD 的 PL 强度被淬灭。
