Photoluminescence Spectroscopy of Quantum Dots, monitored by the Spex FluoroMax

of these ions; and (c) the binary structures of these ions have various lattice constants. Relaxation of the ionic bonds to equilibrium positions may lead to local order in the structure and a larger than expected reduction in the band-gap.


Conclusions
Particle size and composition can control quantum confinement. These QDs may be useful for molecular imaging in living systems, because of their near-IR and far-red fluorescence, where deep-tissue imaging is necessary, away from blood and water light-absorption QDs also provide absorption coefficients an order-of-magnitude larger than typical organic dyes. The ultra-sensitive Spex FluoroMax spectrofluorometer is useful in a wide array of research related to nanostructures and materials science for the future.
