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 …

Birefringent materials are of great importance in optical communication and the laser
industry, as they can modulate the polarization of light. Limited by their transparency range …

Borates are one of the most important classes of functional materials, and several hundreds
of artificial borates have been synthesized. The substitution of oxygen by fluorine leads to …

As a fundamental parameter of the optical crystals, birefringence plays a vital role in many
optical applications, such as phase modulation, light splitting, and polarization, especially …

Pb (II) cations have long been associated with lone-pairs which can help to enhance the
optical anisotropic birefringence. In this paper, the contribution of lead cations to …

Abstract Bulk crystals of Ba 2 Na 3 (B 3 O 6) 2 F (BNBF) have been successfully grown by
top-seeded solution growth (TSSG) technique. Its transmittance spectra show a wide …

In this paper we study the optical properties of a family of borate crystals comprising alpha
and beta barium borates, barium fluoroborate, lithium triborate, and lithium tetraborate in the …

Coprecipitation of nanofluorides in MF 2-RF 3 and NaF-RF 3 (M= Ca, Sr, Ba; R= rare earth
elements) results in the formation of nonequilibrium phases with wide areas of homogeneity …

Two new barium borate fluorides LiBa12 (BO3) 7F4 and NaBa12 (BO3) 7F4 are obtained by
spontaneous crystallization from high-temperature flux. The two compounds are isostructural …
