| 摘要: 采用非热注法成功制备了高质量的油溶性CuInS2/ZnS核壳量子点,量子点的荧光发射峰在可见光到近红外范围内可调(550~800 nm),且荧光量子产率最高达80%。本文进一步利用具有温敏特性的聚丙烯酰胺胶束作相转移剂,成功地将油溶性的CuInS2/ZnS核壳量子点转移入水相。水相中自组装形成的CuInS2/ZnS量子点-胶束复合物不仅具有良好的荧光性质,而且胶束原有的灵敏的热响应性被保留。这些研究初步表明,无镉的低毒的CuInS2/ZnS量子点可作为纳米胶束的荧光示踪探针。 | |

| Abstract: High-quality oil-soluble CuInS2/ZnS core/shell quantum dots (QDs) have been synthesized successfully using a non-hot-injection method. The as-prepared QDs exhibits tunable photoluminescence (PL) emission (PL peak, 550~800 nm) with a maximum PL quantum yield (QY) up to 80%. Furthermore, in this study, we explored further the water transfer of oil-soluble CuInS2/ZnS QDs by using temperature-sensitive poly(N-isopropylacryla-mide-co-Acrylamide-co-Octadecylacrylate) (P(NIPA-co-AAm-co-ODA)) micelle. The QDs-loaded micelle not only shows favorable PL properties, but also maintains the initial sensitive thermal responsibility. These results confirm the promising potential of cadmium-free CuInS2/ZnS QDs as a fluorescent probe for the biological imaging of micelle. | |
