Rb1.87Cs1.13B8O13(NO3): A new acentric borate-nitrate with two different types of three-dimensional interpenetrating lattices

Design of ultraviolet (UV) and deep-UV materials remains a great challenge, especially those with multi-anions. By incorporating [NO3] units into borates, a new alkali metal borate-nitrate Rb1.87Cs1.13B8O13(NO3) with acentric space...
