Excitonic and radiative effects in GaSe-C60 structures
The absorption and photoluminescence spectra of GaSe intercalated in C60 fullerene has been investigated at 293 K and 78 K. C60 and C60-toluene molecules intercalated in-between GaSe stratified “packing” cause the appearance of localized levels revealed in low energy wing of n=1 excitonic of the...

| Sumario: | The absorption and photoluminescence spectra of GaSe intercalated in C60 fullerene has
been investigated at 293 K and 78 K. C60 and C60-toluene molecules intercalated in-between
GaSe stratified “packing” cause the appearance of localized levels revealed in low energy
wing of n=1 excitonic of the absorption and determine the exciton-phonon interaction. It has
been established that C60 and C60-toluene molecules form new recombination levels in GaSe
crystals and determine the 1.7÷1.75 eV photoluminescence band.
