摘要：

The nonlinear optical response of Li1-x(Nb,Ta)1-xWxO3 increases strongly with x. This is explained in terms of changing bond polarizabilities: W-0 bonds are more polarizable than Nb-O/Ta-0 bonds. A W-0 bond polarizability beta(parallel-to) of (570 +/- 130) 10(-40) m4/V is derived, neglecting beta(perpendicular-to). The luminescence properties depend also on x, and new emission and excitation bands are found.
