چکیده انگلیسی
We report on the chemical linkage of fullerenes to lead selenide (PbSe) nanocrystals by exchanging oleic acid ligands on PbSe nanocrystals with C60-bound dithiocarbamate ligands. To improve the solubility of C60-PbSe nanocrystals, a small-molecular-weight dithiocarbamate was used as a co-ligand in the ligand exchange reaction. The as-synthesized C60-PbSe nanoconjugates were characterized by 1H NMR, UV–vis and transmission electron microscopy (TEM). Photoelectrochemistry (PEC) of the C60-PbSe nanoconjugate revealed a reversed polarity of the photocurrent compared to those of C60 and PbSe nanoparticles separately, suggesting that C60 may serve as p-dopants to PbSe nanocrystals through the surface transfer doping process.
