Abstract
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.
