Abstract
K2(NbO)2Si4O12 consisting of trans-connected Nb(V)O6 octahedral chains is a novel nonlinear optical (NLO) material synthesized by Tournoux and coworkers. Our investigation of several inorganic materials containing trans-connected d0:MO6 octahedral chains has identified fresnoite (Ba2TiOSi2O7) as another structure type for second order NLO response. Here we describe the synthesis of a new fresnoite, Ba1.5VOSi2O7, that shows efficient second harmonic generation of 1064 nm radiation, lending support to the idea that trans-connected d0:MO6 octahedra with alternating long and short M¤ O distances is indeed a crucial structural unit for generation of efficient second order NLO response.
