The primary goal of this review is to present a clear chemical perspective of borates in order
to stimulate and facilitate the discovery of new borate-based optical materials. These …

Birefringence is one of key performance for optical functional crystals owing to their
indispensable role in angle phase-matching or adjusting the polarization of light. In the past …

The [B3O6] group as a prime functional unit provides borates with intrinsic properties that
are modified by coordination to cations. Inherent [B3O6] cluster structures in borates …

Birefringent materials play indispensable roles in modulating the polarization of light and are
vital in the laser science and technology. Currently, the design of birefringent materials …

Large second-harmonic generation (SHG) response and broad band gap are two important
and competitive parameters. It is difficult to balance them out in one material. In this work, by …

Deep-ultraviolet nonlinear optical (DUV NLO) crystals are indispensable for solid-state
lasers to produce coherent light with wavelengths shorter than 200 nm, yet their structure …

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 …

Borophosphates are very known for the short ultraviolet (UV) cutoff edge and have become
the promising UV and deep-UV functional crystals candidates; however, tetrahedral [PO4] …

The development of a data‐driven science paradigm is greatly revolutionizing the process of
materials discovery. Particularly, exploring novel nonlinear optical (NLO) materials with the …

Large band gap and strong nonlinear optical (NLO) effect are two valuable but contradictory
parameters, which are difficult to balance in one infrared (IR) NLO material. Herein, the first …
