摘要：

We trapped malachite green dye molecules in a closed-porosity xerogel and measured the absorption recovery time of the S0 --> S1 transition around 620 nm using the pump and probe technique with 100 fs pulses. An increase in the sample transmission from 3% to 40% was induced. From the time constants obtained, we deduce that the molecules are held with an apparent viscosity of about 25 cP. The lifetimes measured, the energy used and the transmission variation are such that this doped xerogel could have potential optical applications.
