Tetrapyrrole derivatives such as porphyrins, phthalocyanines, naphthalocyanines, and
porpholactones, are highly stable macrocyclic compounds that play important roles in many …

The field of nonlinear optics (NLO) has been developing for a few decades as a promising
field with important applications in the domain of photoelectronics and photonics. 1-3 NLO …

We present our results on nonlinear optical (NLO) and optical limiting properties of Tetra tert-
butyl phthalocyanine and Zinc tetra tert-butyl phthalocyanine studied at 633 nm using a …

We report our results on the nonlinear optical and optical limiting properties of two alkoxy
phthalocyanines namely 2, 3, 9, 10, 16, 17, 23, 24-octakis-(heptyloxy) phthalocyanine and 2 …

We report the results on third and second order nonlinear optical susceptibilities of two
natural pigments extracted from spinach. The last were identified by UV–vis spectral …

Third order nonlinear optical properties of a serie of chromophores were investigated using
nonlinear transmission (NLT), degenerate four waves mixing (DFWM) and third harmonic …

The nanosecond optical-limiting characteristics (at 532 nm) of some rare-earth metallo-
phthalocyanines (Sm (Pc) _2, Eu (Pc) _2, and LaPc) doped in a copolymer matrix of poly …

Single crystals of bis-2, 7-diethylaminohepta-2, 5-dien-4-one (BEDO) were grown by the
solution growth method. The material has been synthesized and characterized by FT-IR and …

The syntheses of neodymium (III) 2, 9, 16, 23-tetrakis-(2, 6-di-tert-butyl-4-methylphenoxy)
phthalocyanine (2), bis europium (III) 2, 9, 16, 23-tetrakis-(2, 6-di-tert-butyl-4-methylphenoxy) …

A simple division of close-aperture Z-scan curve by open-aperture Z-scan is conveniently
used to obtain the nonlinear refractive index. It usually causes an error, which even reaches …
