A review of lithium niobate single crystals and polycrystals in the form of powders has been
prepared. Both the classical and recent literature on this topic are revisited. It is composed of …

Electric-dipole optical second harmonic generation (SHG) is a second-order nonlinear
process that is widely used as a sensitive probe to detect broken inversion symmetry and …

Near-infrared (NIR) marker-based imaging is of growing importance for deep tissue imaging
and is based on a considerable reduction of optical losses at large wavelengths. We aim to …

We report a polarization-resolved analysis of the second harmonic intensity collected in retro-
reflection from a Lithium Niobate microcrystals powder. Depth intensity profiles exhibit first …

Exceptionally electron‐rich, nearly trigonal‐planar tricyanidometalate anions [Fe (CN) 3] 7−
and [Ru (CN) 3] 7− were stabilized in LiSr3 [Fe (CN) 3] and AE3. 5 [M (CN) 3](AE= Sr, Ba; …

Random granular media can exhibit characteristics that are often related to ordered media.
In the present work, this feature is observed in the polarized Second Harmonic Generation …

Changes in structural and magnetic properties have been systematically induced in lithium
niobate (LiNbO3) powders, Fe-doped with different concentrations and thermally treated in …

Disentangling Second Harmonic Generation (SHG) and Multiphoton Excited
Photoluminescence (MEPL) signals in microscopy experiments is not an easy task. Two …

To solve the problem that lithium niobate is difficult to process into microspheres, a method
of spheroidizing lithium niobate powder twice by radio-frequency inductively coupled …

Abstract Second Harmonic Generation (SHG) and Multiphoton Excited Photoluminescence
(MEPL) are observed in retro-reflection mode from a 22 nm diameter anatase TiO 2 …
