Abstract
Quantum dots (QDs) are semiconductor nanoparticles with very interesting optical
properties, like high quantum yield or narrow and size-tunable fluorescence spectra.
Current applications of QDs are wide-spread, their use as fluorescence labels in
bioassays being one of the most promising applications. CdSe semiconductor
nanoparticles (NPs) have been prepared by the organometallic pyrolysis method
developed by Murray et al , and modified by Peng et al. The formation of the quantum dot
nanoparticles have been clearly seen in the TEM images. Powder X-ray diffraction (XRD)
has confirmed the structure of the products. In addition, the crystalline phase and the size
distribution of the nanocrystals have been determined by XRD and TEM, respectively
.The optical properties have been assessed by UV-Vis measurements.
Keywords: Nanoparticles, Quantum dots, TEM, XRD.
Contribution of study
Synthesis, Characterization and Optical Properties of CdSe Quantum Dots.
