Abstract :
This work reports on degenerate nonlinear absorption spectrum from 725 to 1000 nm for bis (n-butylimido) perylene (BuFTCD), bis (benzimidazo) perylene (AzoPTCD), bis (benzimidazo) thioperylene (Monothio BZP), and n-pentylimido-benzimidazo perylene (PAzoPTCD) solutions. Nonlinear optical measurements were carried out with the Z-scan technique, which is a simple and sensitive method to determine the 2PA cross-section values.
