Title: Crystal structures and second-order NLO properties of borogermanates

Abstract

Borogermanates are a class of very important compounds in materials chemistry. In this paper, the syntheses, structures, and properties of metal borogermanates are reviewed. Organically templated borogermanates with zeolite-like open-frameworks show potential applications as microporous materials. Many compounds in alkali or alkaline-earth borogermanate systems are structurally acentric or polar, some of which exhibit excellent Second Harmonic Generation (SHG) coefficients, wide transparency regions, and high optical-damage thresholds as well as excellent thermal stability. Most of the lanthanide borogermanates are structurally centrosymmetric and not SHG active; however, they are able to emit strong luminescence in visible or near-IR region. In the B-rich compounds, BO{sub 3} and BO{sub 4} groups can be polymerized into a variety of discrete polynuclear anionic cluster units or extended architectures via B-O-B bridges; whereas in the Ge-rich compounds, GeO{sub 4} and GeO{sub 6} polyhedra can also be polymerized. The combinations of borate and germinate afforded rich structural and topological types. - Graphical abstract: Borogermanates are a class of very important compounds in materials chemistry. Both BO{sub x} (x=3, 4) and GeO{sub y} (y=4, 6) polyhedra can be polymerized into a variety of discrete polynuclear anionic cluster units or extended architectures. The combinations of borate and germanate groups inmore » the same oxide framework not only give rise to a rich structural chemistry, but also afford many polar compounds with good SHG properties. Highlights: Black-Right-Pointing-Pointer Borogermanates are a class of new materials. Black-Right-Pointing-Pointer They feature to be the combination of B and Ge atoms into the same oxide framework. Black-Right-Pointing-Pointer They can form a large number of novel 2D and 3D framework structures. Black-Right-Pointing-Pointer Some of them are acentric or polar with moderate strong SHG responses.« less
