The combination of SnII or SbIII with π, non‐π‐conjugated units has produced birefringent
crystals with birefringence ranging from 0.005 to 0.468@ 1064 nm. It is proven that …

Planar π-conjugated groups that possess not only large hyperpolarizability but also optical
anisotropy are proved to be good functional motifs for optical materials with outstanding …

Borate crystals can be chemically and functionally modified by the fluorination strategy,
which encourages the identification of emerging fluorooxoborates with a structure and set of …

Noncentrosymmetric (NCS) structures are of particular interest owing to their symmetry-
dependent physical properties, eg, pyroelectricity, ferroelectricity, piezoelectricity, and …

Second‐harmonic generation (SHG) is a fundamental optical property of nonlinear optical
(NLO) crystals. Thus far, it has proved difficult to engineer large SHG responses, particularly …

Performance enhancement induced by structural modification has long been the target in
materials science fields. Direct evidence to witness the effectivity of one strategy is …

The exploration of antilaser damage wide bandgap infrared (IR) nonlinear optical (NLO)
materials is urgent but challenging. Herein, by introducing the idea of fluorination into …

Short-wavelength optical crystals are the key components of optical devices, but only a few
crystals can be used in practical applications. In recent years, the emergence of …

Deep-ultraviolet (DUV) coherent light is urgently needed for many important technological
applications such as lithography and advanced scientific instruments. Its generation …

Structural alteration based on existing molecules is an effective way to study new
substances. However, a limited control range results, especially when the band gaps are …
