Published: Feb. 7, 2024

Abstract Sulfates with a large bandgap are always promising optical candidates. However, due to insufficient birefringence, their applications restricted. Here, in terms of this deficiency, two strategies proposed rationally modulate the anisotropy sulfates by cations and anions, respectively. For cation modulation, [C(NH 2 ) 3 ]Al(SO 4 ·6H O crystal is investigated, which exhibits an unprecedented birefringence (0.098 @ 546 nm) compared other deep‐ultraviolet transparent sulfates, resulting from synergy π‐conjugated ] + non‐π‐conjugated [SO 2− groups. anion novel functional group, [S 6 , polarizability anisotropy, designed. Thus, new crystal, NaKS obtained, 0.130 nm short ultraviolet absorption cutoff edge 215 nm. These results confirm validity strategies. Therefore, play important role improving sulfate's then promoting potential advanced systems.

Chalcogenides are promising candidates for exploring mid- and far-infrared nonlinear optical (NLO) materials. Nevertheless, although tellurides possess greater advantages in the above-mentioned spectral regions, reports on telluride NLO materials far fewer than those sulfides selenides. In this work, a new quaternary NLO-active telluride, KCd4Ga5Te12, was discovered, its Rb Cs analogues were successfully synthesized. They crystallized trigonal R3 space group structure features 3D diamond-like framework constructed by vertex-sharing asymmetric MTe4 tetrahedra (centered disordered Cd Ga) that stacked along c-axis. Moreover, comprehensive study of their IR properties, photoluminescence structural performed.
