水溶性的InP-ZnS核壳荧光量子点

一种InP/ZnS核壳结构量子点及制备方法

       摘要：公开了一种InP/ZnS核壳结构量子点的制备方法。

       选用以醋酸铟或者三氯化铟作为铟源、以十一烯酸锌、脂肪酸锌或者长链脂肪酸锌作为锌源，真空抽气操作，在一个反应器中制备In3+与Zn2+摩尔比为1∶1～5∶1的In、Zn混合前体溶液，通过向反应液中滴加S前体溶液，反应制得InP/ZnS核壳结构量子点。合成工艺简单，繁琐的抽真空操作，省去了再次添加用于包壳的锌源的步骤，所制的未包壳的InP量子点荧光量子产率为4～7.5％，所制InP/ZnS核壳结构量子点，其荧光发射峰在511-642nm之间可控调节，荧光发射峰半高宽为52～93nm，且荧光稳定性和量子效率相对于包壳前有，荧光量子产率达20～40％。
