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.
