In-situ Preparation of Purple-Emitting CdS Quantum Dots Using Inner PAMAM Dendrimer Templates

CONG Ri-Min LUO Yun-Jun* LI Guo-Ping TAN Hui-Min(School of Material Science and Engineering Beijing Institute of Technology, Beijing 100081)  
Well-dispersed CdS quantum dots (QDs) with narrow size-distribution were prepared using generation 4.5 ester-terminated PAMAM dendrimers as inner-templates. The average diameter of CdS QDs was 1.5 nm and the photoluminescence was purple. The room temperature photoluminescence quantum yield (RT-PQY) was 0.015. The diameter of CdS QDs increased with the increase of n / nPAMAM, also the color of photoluminescence was tunable and could be changed from purple to blue.
