EFFECT OF REACTION TEMPERATURE AND STIRRING TIME ON THE FL INTENSITY OF A NOVEL BIOPOLYMER CAPPED CDTE QDS

A novel biopolymer capped CdTe quantum dots (QDs) was synthesized by polyacrylamide (PAAm) grafted onto sodium alginate (Alg-g-PAAm) is introduced. Transmission electron microscopy images revealed that the obtained QDs are nearly spherical in shape with average diameter of 4 nm. Finally, the effect of the reaction temperature and stirring time on the optical properties of the CdTe- Alg-g-PAAm was examined
