Quantum lattice fluctuations and luminescence in C60.
نویسندگان
چکیده
We consider luminescence in photo-excited neutral C60 using the Su-SchriefferHeeger model applied to a single C60 molecule. To calculate the luminescence we use a collective coordinate method where our collective coordinate resembles the displacement of the carbon atoms of the Hg(8) phonon mode and extrapolates between the ground state ”dimerisation” and the exciton polaron. There is good agreement for the existing luminescence peak spacing and fair agreement for the relative intensity. We predict the existence of further peaks not yet resolved in experiment. PACS Numbers : 78.65.Hc, 74.70.Kn, 36.90+f Present and permanent address.

Quantum phases and fluctuations in correlated electron systems with frustration and competing interactions are reviewed. In the localized moment case the S=1/2 J1 - J2 - model on a square lattice exhibits a rich phase diagram with magnetic as well as exotic hidden order phases due to the interplay of frustration and quantum fluctuations. Their signature in magnetocaloric quantities and the hig...
متن کاملQuantum Mechanical Calculations of Photovoltaic and Photoelectronic Properties of Oligoselenophene/Fullerene BHJ Solar Cells
To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...

In this report, we present a facile approach for the synthesis of luminescent CdS and CdS:Mn+2 nanocrystals by reaction of CdSO4 and Na2S2O3 in the presence of thioglycerol (C3H8O2S) as capping agent. The influence of various experimental variables including, pH values and percentage of dopant, on the growth...
متن کاملMotion of CO Molecules in Solid C60 Probed by Solid-State NMR
Polycrystalline C60 has been intercalated with 99 atom % 13C-enriched CO gas by using highpressure, high-temperature synthesis. The ratio of 13CO to C60 is determined using 13C NMR under magicangle spinning and is found to be almost 1:2. Static solid-state 13C NMR spectra of 13CO-intercalated C60 have been measured in the range between room temperature and 4 K. In the high-temperature range, i....
