Preparation and Characterization of Highly Fluorescent TGA-CdTe Quantum Dot-Hyamine 1622 Additive Composite

摘要

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 ~(13)C 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.
