High quality PbSe and PbTe nanocrystals were synthesized with non-injection one-pot method which could be scale up easily. The use of traditional dangerous pyrophoric trioctylphosphine (TOP) and tributylphosphine (TBP) reagents was avoided. The crystal size was controlled by the reaction time and temperature, and the shape (sphere and cube) was controlled by the use of different combinations of surfactants...
In this paper, several amphiphilic oligomers were synthesized using a low molecular weight polymaleic anhydride and different aliphatic alcohols. Water-soluble Au/Ag noble nanocrystals (NCs) were then prepared by an organic-aqueous phase transfer method with appropriate amphiphilic oligomers based on surface-bound interactions. The obtained water-soluble Au/Ag NCs have the same visible color and UV–vis...
We report a simple, robust, reproducible and phosphine-free approach to synthesize zinc-blende HgS nanocrystals with both flower and dot shapes at moderate temperatures. 1-Octadecylamine was used to effectively adjust the activity of mercury ions. HgS nanoflowers were synthesized with S precursors prepared at temperatures between 100°C and 210°C, while individual dot-shaped HgS nanocrystals were obtained...
