Spectroscopy and femtosecond dynamics of type-II CdSe/ZnTe core-shell semiconductor synthesized via the CdO precursor

Article Abstract:

CdSe/ZnTe type-II quantum dots (QDs) synthesized through the CdO precursor is discussed, where spectroscopic and femtosecond dynamic measurements disclose the rate of photoinduced electron/hole spatial separation decreases with increases in the size of the core, and it is independent of the thickness of the shell in the CdSe/ZnTe QDs. The findings are consistent with the binding strength of the electron and hole confined at the center of CdSe.

Effects of the solute model and concentration on the calculated free energy of hydration in explicit solvent solution

Article Abstract:

Effects of the atom model and the atomic charge parameters on the calculated free energy of hydration (FEH) are studied for CH3OH, CH3NH2, CH3CN, and N(CH3)sub3 with the all atom vs the united-atom model for the CH3 group. The all-atom model, in combination with solute charges derived on the basis of the SCIPCM/B3LYP/6-31G* ELPO, predicts too negative hydration free energies for CH3NH2 and CH3CN.

Spin states of C(sub 60)(super 3-) and C(sub 120)O(super n-) (n=2, 3, 4) anions using electron spin transient nutation spectroscopy

Article Abstract:

Electron spin transient nutation (ESTN) measurements performed with phase inverted echo amplitude nutation is reported. The advantage of this method is that all echoes can be detected at the same time, thus minimizing loss of resolution because of relaxation broadening and also minimizes distortions arising from spectrometer deadtime.
