油溶CdS-ZnS荧光量子点（表面修饰氨基/羧基/油酸）
油溶CdS-ZnS荧光量子点（表面修饰氨基/羧基/油酸）
CdS/ZnS量子点优势：
光学性能对粒子尺寸的依赖性是量子点独特的和具吸引力的功能。例如，通过控制粒子的大小，CdSe量子点的发射光波长在整个可见光范围内连续可调。然而，二元素量子点，如CdSe量子点，有两个缺点。*，其表面缺陷形成表面陷阱态，使发光效率和稳定性降低。通过在量子点表面包附ZnS，形成Core-shell结构可以降低面缺陷，但CdSe和ZnS晶格失配，在很大程度上影响其发光效率和光学稳定性。第二，量子点的消光系数同粒子的体积成正比例关系。标记6nm（红光）CdSe量子点的物质发射光强度是2nm（绿光）量子点的三十倍，这会引起检测灵敏度的差异。
不同于二元素量子点，本公司研发的梯度合金CdS/ZnS量子点，在发光核和ZnS壳中加入三元合金过渡组分，因而带来了以下几个优点：
1、通过调整合金元素组成控制其光学性能，制备体积*但发光频率不同的量子点，从而降低由于应用不同颜色量子点引起的检测灵敏度上的差异；
2、合金量子点晶格力度强，性能稳定；
3、实现晶格的逐步过渡，有效降低量子点晶格缺陷造成的内部压力，从而使量子点具有较高的发光效率和稳定性。
