摘要 采用二巯基辛酸修饰ZnS-AgInS2型量子点,建立了一种制备水溶性量子点的方法,得到了性能优良的水溶性量子点.该修饰方法简便易行,具有较高的转化率;得到的量子点荧光性能损失较小,可以稳定放置6个月. A novel method for the preparation of water-soluble quantum dots(QDs)was established by modifying ZnS-AgInS2 quantum dots with dihydrolipoic acid(DHLA).This approach is simple and convenient and has a relatively high conversion rate.The hydrophilic quantum dots obtained show little loss in fluorescence quantum yield compared with the original hydrophobic quantum dots.The DHLA-modified QDs can keep stable for 6 months.
