Cd₂Nb₂Te₄O₁₅: A Novel Pseudo‐Aurivillius‐Type Tellurite with Unprecedented Nonlinear Optical Properties and Excellent Stability (Small 39/2023)

Grafting-Assisted Engineering A new nonlinear optical (NLO) material, Cd2Nb2Te4O15, features a pseudo-Aurivillius-type perovskite layered structure composed of three types of NLO active groups, including CdO6 octahedron, NbO6 octahedron, and TeO4 seesaws, which exhibit a giant cond-harmonic generation (SHG) response, a large band gap, a wide optical transparency window, superior birefringence, high laser-induced damage threshold (LIDT) and strong acid and alkali resistance.
