In the first quarter of the twentieth century, one of the most significant events in physics and
chemistry was the establishment of the quantum theories of radiation, matter, and their …

This review gives an overview concerning the optical limiting (OL) properties of materials
like porphyrins and phthalocyanines. It gives special attention to the phthalocyanine and …

Almost three decades ago, the field of nonlinear optics evolved with the discovery of lasers.
In the beginning, nonlinear optical (NLO) phenomena were investigated in inorganic …

This book is a revised edition of a book by the same author, Conducting Polymers,
Fundamentals and Applications: A Practical Approach, published in 1999 and well received …

Pure C 60 was deposited on optical substrates in vacuo and spectroscopically
characterized. A small linear absorption coefficient α= 6 cm− 1 was measured at 1.064 μm …

These and other objects are Satisfied by the present invention, which provides a new class
of optical devices wherein optical waveguide elements are coupled by intro ducing an …

We haveused picosecond third harmonic generation spectroscopy to investigate the third-
order optical nonlinearities of a series of 12 systematically designed homopolymers and …

One of the intrinsic properties of CNTs relied on for drug delivery is the ability of these
materials, with sub-cell dimensions, to quite easily penetrate various cellular and other …

Off-resonant third-order nonlinear optical susceptibilities using degenerate four-wave mixing
measurements in solution at 1.064 pm are reported for partially doped states of the soluble …

Various polyimides and polyamides have recently been prepared via hydrothermal
synthesis in nothing but H2O under high‐pressure and high‐temperature conditions …
