A controlled approach for synthesizing CdTe quantum dots polyamidoamine nanocomposites
چکیده انگلیسی

We develop a controllable approach to prepare ordered–CdTe quantum dots (QDs) polyamidoamine (PAMAM) nanocomposites (NCPs) by self-assembly growth of simple CdTe– PAMAM in aqueous solution. The sphere and network CdTe NCPs were obtained at pH 4.7 for growing 15 h and 79 h respectively. As the NCPs ceased growing over pH 8 immediately, we can conveniently control their size and morphology by adjusting pH of the solution to tune the growth time. The morphology change of CdTe-PAMAM nanocomposites was characterized by TEM images. The fluorescent intensity and photostability of ordered–CdTe–PAMAM have been improved significantly.
