FIG. 1.

(a) Schematic presentation of the experimental setup. The microreactor was mounted on a high precision stage on a Huber 410 goniometer. The beam position and temperature distribution were monitored by CCTV and IRTV cameras, respectively. Fluorescence x ray was detected by a compact silicon drift diode detector. Flows 1–3 correspond to TOP-Se, Cd stock solution, and DDA, respectively. (b) The positions and temperatures of four points along the microreactor channel as measured in the EXAFS experiment.

FIG. 2.

(a) Se -edge EXAFS functions at points A, B, C, and D, along with those of the TOP-Se solution and CdSe powder measured at room temperature. (b) The corresponding Fourier transform magnitudes of the -weighted functions.

FIG. 3.

(a) UV-visible absorbance spectra of CdSe nanoparticles as a function of time after injection of the reactants. (b) The fraction of consumed TOP-Se in the nucleation process and as a function of . The solid lines in (b) are guides to the eye.
