油溶CdS-ZnS熒光量子點(diǎn)（表面修飾氨基/羧基/油酸）

油溶CdS-ZnS熒光量子點(diǎn)（表面修飾氨基/羧基/油酸）

CdS/ZnS量子點(diǎn)：

光學(xué)性能對粒子尺寸的依賴性是量子點(diǎn)的和具力的功能。例如，通過控制粒子的大小，CdSe量子點(diǎn)的發(fā)射光波長在整個(gè)可見光范圍內(nèi)連續(xù)可調(diào)。然而，二元素量子點(diǎn)，如CdSe量子點(diǎn)，有兩個(gè)缺點(diǎn)。*，其表面缺陷形成表面陷阱態(tài)，使發(fā)光效率和穩(wěn)定性降低。通過在量子點(diǎn)表面包附ZnS，形成Core-shell結(jié)構(gòu)可以降低面缺陷，但CdSe和ZnS晶格失配，在程度上影響其發(fā)光效率和光學(xué)穩(wěn)定性。，量子點(diǎn)的消光系數(shù)同粒子的體積成正比例關(guān)系。標(biāo)記6nm（紅光）CdSe量子點(diǎn)的物質(zhì)發(fā)射光度是2nm（綠光）量子點(diǎn)的三十倍，這會引起檢測靈敏度的差異。

不同于二元素量子點(diǎn)，本公司的梯度合金CdS/ZnS量子點(diǎn)，在發(fā)光核和ZnS殼中加入三元合金過渡組分，因而帶來了以下幾個(gè)：

1、通過調(diào)整合金元素組成控制其光學(xué)性能，制備體積*但發(fā)光頻率不同的量子點(diǎn)，從而降低由于應(yīng)用不同顏色量子點(diǎn)引起的檢測靈敏度上的差異；

2、合金量子點(diǎn)晶格力度，性能穩(wěn)定；

3、實(shí)現(xiàn)晶格的逐步過渡，降低量子點(diǎn)晶格缺陷造成的內(nèi)部壓力，從而使量子點(diǎn)具有較的發(fā)光效率和穩(wěn)定性。
