Abstract

One new combination, alkali-metal and alkaline earth-metal selenite fluoride, LiBa₃Bi₆(SeO₃)₇F₁₁ (LBBSF) and its analogue Ba₃Bi_6.5(SeO₃)₇F_10.5O_0.5 (BBSF) were reported here for the first time. Unusual aliovalent cation substitution between them affected the layer thickness and made the bond strains of [SeO₃] enhanced, thereby inducing greater distortions and affecting the SHG efficiencies. This work may provide thoughts for exploring new NLO materials.
