Synthesize of a novel CdTe quantum dots capped by polyacrylamide grafted onto phosphate starch

In this work, polyacrylamide grafted onto phosphate starch (PAAm-g-ps-starch) as a biopolymer was synthesized and applied for surface modification of water soluble CdTe quantum dots (QDs). The effects of AAm concentration on optical properties of CdTe QDs were investigated via fluorescent (FL) and UV- visible spectra. The results showed that the PS-g-PAAm significantly affects the optical properties of CdTe QDs. The obtained samples were characterized by transmission electron microscopy (TEM).
