Ba5Y12Zn[O(SiO4)]8: a novel non-centrosymmetric silicate with a short ultraviolet cut-off edge featuring [ZnSi4O16] and [SiO4] units

A new silicate Ba 5 Y 12 Zn[O(SiO 4 )] 8 was synthesized by a high-temperature solution method and experimental results show a short cut-off edge of 204 nm, an SHG response (0.3 × KDP), and thermal stability. Meanwhile, the effect of the n M : n Si ratio on the Si–O framework was studied.
