Quasi‐Resonance in Hydrostatically Compressed Isotopic Mixed Crystals of Deuteronaphthalene

Localized and Extended Exciton States in Solid C60 Studied by Photoluminescence at High Pressure

“…In view of this some bands in the photoluminescence spectrum may be associated with the extended exciton states and their assignment needs special experiments. These may be photoluminescence studies at high pressure as the pressure-induced shift of the extended and localized exciton states in molecular solids has quite different nature and value [10,11].…”
