Carboxyl end-functionalized poly(3-hexylthiophene) (P3HT-COOH) was grafted chemically with CdSe nanocrystals (NCs) by a phosphine-free method. The particle quality of P3HT-COOH/CdSe nanocomposites was better than that of P3HT/CdSe nanocomposites, which were synthesized using the same method. Nanocrystals with controllable particle size exhibited a wurtzite crystalline structure and showed excellent nanocrystal dispersion in the P3HT-COOH matrix. Photoluminescence (PL) characterization performed on nanocomposites suggested the efficient charge transfer at the P3HT-COOH/CdSe interface. This approach based on the phosphine-free method is not only environmentally friendly but also highly efficient.

Doped Carbon Dots

Europium (Eu) doped carbon dots (CDs) were synthesized via a rapid and simple microwave mediated method using polyethylene glycol (PEG) as a precursor, and characterized in detail. The results were that these as-prepared CDs showed a uniform and small particle size, and exhibit good photostability and high photoluminescence quantum yields. Additionally, it also found that the doped Eu would change the fluorescence properties, which indicates potential applications in the field of biolabeling.
