Synthesis of spherical CdSe nanocrystals: To synthesize red fluorescent CdSe QDs, TOPO (3.00 g), ODPA (0.28 g) and CdO (0.06 g) were placed in a three necked round bottom flask and degassed at 150 oC for 1 h. The reaction mixture was then heated to 370 oC under N2 atmosphere. After the formation of the Cd-ODPA complex at around 300 oC, the solution turned from reddish to colourless. At this point 1.5 g of TOP was injected. After reaching the desired temperature, a TOPSe solution (58 mg of elemental Se in 360 mg of TOP) was injected quickly (
