Abstract:
Objective: The aim of the present study was to prepare highly luminescent additive composite
polymer with hyamine 1622 and Thioglycolic Acid (TGA) coated CdTe Quantum Dots (QDs).
Methods: The additive nano-composite was synthesized by the colloid synthesis method for the first
time. The properties like particle size, fluorescence efficiency, fluorescence imaging, self-assembling,
quantum dots, encapsulation, etc. were characterized by the employing of instrumental techniques
such as 1H and 13C NMR, Fourier Transform Infrared spectroscopy (FT-IR), BAB image analysis system
spectroscopy, Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) and
Energy Dispersive X-Ray Spectroscopy (EDS).
Results: CdTe quantum dots were stabilized successfully in the solid phase by hydrophobic conversion
with hyamine 1622 as the cationic surfactant. The experimental results show that the prepared
composite is ideal for various applications, easily synthesized, safe, and maintain good fluorescence
properties.
Conclusion: The newly prepared additive nanocomposite having sharp and narrow excitation/
emission properties is expected to be applicable in biomedical/analytical systems.
