The Birefringence Modulation in Short‐Wave Ultraviolet Sulfates with Functional π‐Conjugated Cations and Polymerized Heteroleptic Tetrahedral Anions

Advanced Optical Materials, Journal Year: 2024, Volume and Issue: 12(14)

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.

Abstract Birefringent crystals have essential applications in optical communication areas. Low‐dimensional structures with inherited structural anisotropy are potential systems for investigating birefringent materials large birefringence. In this work, the zero‐dimensional (0D) [( p ‐C 5 H NO) 2 ZnCl ] ( 1 ) and [ 6 NO] [ZnCl 4 were obtained by introducing π‐conjugated NO (4HP) into three‐dimensional (3D) . Remarkably, exhibits a giant birefringence of 0.482@546 nm, which is largest among Zn‐based ultraviolet (UV) compounds 160 times that According to theoretical calculation analyses, polarizability, high spatial density, ideal distribution [(4HP) 0 cluster, low dimension result dramatically increased compared This work will provide valid route accelerating design synthesis excellent low‐dimensional systems.

Exploring new nonlinear optical (NLO) crystals for the output of deep-ultraviolet (DUV) lasers via frequency conversion technique is great interest. Monofluorophosphate a chemical system exploring DUV NLO while difluorophosphate still lacking in research but attracting attention. Herein, proved as potential member materials based on high-throughtput crystal structure prediction combined with first-principles calculations.
