Double second-order Jahn-Teller strategy driven NLO response in sulfate crystal Nb2O2(TeO3)2(SO4) with a large birefringence
{{output}}
Nonlinear optical (NLO) crystals serve as indispensable components in laser technology. Many modifications of sulfate-based NLO materials rely on introducing a single type of functional cation, which in some cases leads to an imbalanced improvement in either N... ...
