Abstract :
A two-beam pump–probe Z-scan method is proposed to investigate nonlinear absorption induced solute migration in CuPcTs/DMSO solution. The ‘pure’ mass transport phenomenon is observed by this method. Moreover, the population density distribution of the solute molecules can be deduced by measuring the transmittance of the sample. Different input pulse energy at different repetition rates are used to investigate the excited state absorptions induced solute migration. Additionally, an energy-gradient induced mass transport model is used to explain the experimental results.
