- Opis:
- Photoinduced effects in pure C$\text{}_{60}$:C$\text{}_{60}$-TTF and C$\text{}_{60}$-2-thioxo-1,3-dithiole cycloadducts are investigated using nonlinear optical techniques. We have studied photoinduced optical second harmonic generation, two-photon absorption, linear electro-optics, and quadratic electro-optic effect coefficient versus applied pressure (p) and temperature (T). We deduce the influence of the grafted substituents in pure C$\text{}_{60}$ on the observed photoinduced effects. The obtained results illustrate clearly that the photoinduced nonlinear optics can be used as a tool to detect structural changes at low temperature in modified C$\text{}_{60}$. We have unambiguously demonstrated that, under the applied hydrostatic pressure up to 19 GPa and the temperature from 4.2 up to 150 K, the observed effects are essentially caused by the grafted TTF derivatives.zapisz i p
