摘要：

We report here fluence dependent transmission and optical limiting of 527 nm, 20 ns laser pulses in tetraphenylporphyrins. Significant decrease in the transmission in zinc(II) tetraphenylporphyrin (ZnTPP) and vanadium(IV)-oxide tetraphenylporphyrin (VOTPP) solutions in toluene was observed with increasing input fluence. We attribute the observed nonlinear absorption in these metalloporphyrins to RSA mechanism which arises due to higher absorption from their excited states than from the ground state, The observed optical limiting in ZnTPP and VOTPP solutions was found to be comparable to that in C-60 solution in toluene.
