Abstract
A large increase in the piezo-optical tensor components IIXXXX was observed in composite films of fullerene derivatives added to a polyvinylalcohol (PVA) matrix at a concentration of 4.6 wt%. The piezo-optical coefficient IIXXXX was dependent on the applied mechanical stress. Simultaneously performed measurements on pure fullerene derivative films and PVA matrices do not show such a large increase in IIXXXX values. Semi-empirical quantum chemical calculations of piezo-optical susceptibilities show that trapping levels between the chromophore fullerene-like molecule and the surrounding polymer play a key role in the observed dependencies.
