Se2(B2O7): a new type of second-order NLO material.
Exploration on the compounds in the selenite-borate system led to the discovery of a new second-order NLO material, Se2B2O7, with a SHG efficiency of about 2.2 times that of KDP (KH2PO4). Its structure features a 3D network with helical tunnels, and it is transparent in the UV and visible region. The compound is a wide band gap semiconductor.
