CdSe nanocrystals were synthesized in tributylphophine (TBP) and tri-n-octylphosphine (TOPO) solvent by using a soft chemistry method. In contract to other methods, the reagent was injected several times while keeping the temperature over a period of time. TEM, AFM UV-vis were used to show the structure character of the nanocrystals. The formation mechanism of the nanocrystals was also discussed. The as-synthesized nanocrystal is shaped like a triangle cone with nearly equal sides of 60nm.
