摘要：

The emission and optical limiting properties of two new organic compounds have been experimentally investigated. Pumping by picosecond and nanosecond lasers, respectively, these two compounds possess strong two-photon absorption and optical limiting effects. The results of time-resolved fluorescence of them in DMF solvent at the different concentrations and small quantum yields indicate that the non-radiation process and reabsorption result in the low emission efficiency of these new molecules with large two-photon absorption (TPA) cross-sections.
