摘要:

Intense white photoluminescence from C60composite films observed under green laser irradiation is found to be closely connected with local defective structures incidentally formed during the film fabrication process. On the basis of the finding, we succeeded in introducing such emissive structures by intentional mechanical scratching. White electroluminescence was also observed at such modified structures. A possible mechanism of such unusual light emission is discussed.
