Determination of the Triplet State Lifetime of C60 /Toluene Solution and C60 Thin Films by Pump-Probe Method
Abstract: Excited state lifetimes of C60/toluene solution and C60 films macromolecular were measured by pump-probe method. Relation between optical switching effect of material and pulse width of pumping field is briefly described. It is found that the faster switching speed of light is, the triplet state lifetime is shorter. A He-Ne laser, as a probe, passed through the sample in the pump-probe experiment. All-optical switching effect was realized. Changing the optical power of the pumping field, switching response of the sample and modulation depth were investigated. In certain experimental conditions, relation between transmission through the sample and response were measured by an oscilloscope. Triple state lifetime of the molecule is speculated. The result showed that C60/toluene solution and C60 film have a fast response time. They would be utilized in some applications, such as optical switches, photonic devices.
