The control of luminous radiation has extremely important implications for modern and future
technologies as well as in medicine. In this Review, we detail chemical structures and their …

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 article presents our comprehensive study in the new area of nanophotonics, which
deals with optical processes at the nanoscale, much smaller than the wavelength of optical …

The first hyperpolarizability of aqueous suspensions of polyphosphate stabilized CdS
nanocrystals of different mean sizes and of Cd x Zn1-x S nanocrystals (x= 0, 0.25, 0.75, 1) …

Abstract Cubic Zn x Cd 1− x S nanoparticles (NPs) synthesized by chemical precipitation
method with average crystallite size of 2.9±0.2 nm were characterized using X-ray diffraction …

The emerging field of coherent nonlinear near-field scanning optical microscopy (NSOM) is
reviewed. Second harmonic, third harmonic, and sum frequency generation (SHG, THG, and …

We present high resolution two-photon excitation microscopy studies combining two-photon
fluorescence (TPF) and second harmonic generation (SHG) in order to probe orientational …

Nanophotonics, defined as nanoscale optical science and technology, is a new
multidisciplinary frontier. This article presents our studies on nanoscale matter–radiation …

Second-harmonic generation and sum-frequency generation with photon scanning
tunneling microscopy and shear-force detection are used to map the nonlinear optical …

We describe an apertureless scanning near‐field optical microscope (SNOM) based on the
local second‐harmonic generation enhancement resulting from an electromagnetic …
