BaNbO(IO3)(5): A New Polar Material with a Very Large SHG Response
By combination of Nb5+ (having a d(0) electronic configuration) and the tone-pair-containing iodate anion, a new SHG material, BaNbO(IO3)(5), has been prepared. It exhibits a very large SHG response (similar to 14 times that of KH2PO4 and similar to 660 times that of alpha-SiO2) and is phase-matchable, The material has high thermal stability and a wide transparent region.
