Abstract
The optical limiting action of C60Ph5Cl and C60Cl6 in solid host has been investigated at 532 nm with nanosecond pulses. The limiting thresholds for C60Ph5Cl and C60Cl6, were 8 J/cm2 and 7 J/cm2, and the linear transmittances were 22 % and 50 %, respectively. These results were compared with previous work, which was carried out on C60Ph5Cl and C60Cl6 molecules in toluene solutions. It was found a fair agreement between the two cases (solution and solid). This behavior can be understood on the basis of the reverse saturable absorption mechanism which determines the optical limiting properties of the C60Ph5Cl and C60Cl6 molecules. Such lower limiting thresholds make these compounds good candidates for optical limiting materials.
