Hg₃(Te₃O₈)(SO₄): a new sulfate tellurite with a novel structure and large birefringence explored from d¹⁰ metal compounds

Abstract

Our explorations of novel inorganic solids with large birefringence in d10 Metal-Te4+-SO42- system afforded four new sulfate tellurites, Ga2(TeO3)(SO4)(OH)2, In2(TeO3)2(SO4)(H2O), Zn4(Te3O7)2(SO4)2(H2O) and Hg3(Te3O8)(SO4). Notably, Hg3(Te3O8)(SO4) exhibits the largest birefringence at...

Hg2(SeO3)(SO4): the first sulfate selenite with large birefringence explored from d10transition metal compounds

“…It has been reported that the birefringence of a compound is inversely related to the band gap of the structure. 19,53–56 As shown in Fig. 5, Hg 2 (SeO 3 )(SO 4 ) exhibits the narrowest band gap among the three compounds.…”

“…, Y 2 (Te 4 O 10 )(SO 4 ), 18 Ga 2 (TeO 3 )(SO 4 )(OH) 2 and Hg 3 (Te 3 O 8 )(SO 4 ). 19 It is worth noting that Hg 3 (Te 3 O 8 )(SO 4 ) exhibits the largest birefringence at 532 nm (0.184) and 1064 nm (0.166) in these reported metal sulfate tellurites.…”

“…16 Recently, our group reported a series of inorganic oxides with large birefringence and wide band gaps via the combination of tellurite groups and sulfate tetrahedra, 17 i.e., Y 2 (Te 4 O 10 )(SO 4 ), 18 Ga 2 (TeO 3 )(SO 4 )(OH) 2 and Hg 3 (Te 3 O 8 )(SO 4 ). 19 It is worth noting that Hg 3 (Te 3 O 8 )(SO 4 ) exhibits the largest birefringence at 532 nm (0.184) and 1064 nm (0.166) in these reported metal sulfate tellurites.…”

“…It has been reported that the birefringence of a compound is inversely related to the band gap of the structure. 19,[53][54][55][56] As shown in Fig. 5, Hg 2 (SeO 3 )(SO 4 ) exhibits the Assuming that every unique selenite group pointed in a different direction, the number of the unique Se(IV) atoms can be used to evaluate the degree of the birefringence qualitatively.…”

SbHPO3F: 2D van der Waals Layered Phosphite Exhibiting Large Birefringence

“…In addition, tetrahedral groups have a wide UV transmission window, which is beneficial to obtain UV and deep-UV optical compounds . However, compared with π-conjugated genes, the non-π-conjugated tetrahedral genes, like (BO 4 ) 5– , (PO 4 ) 3– , , and (SO 4 ) 2– − have T d symmetry, which is not beneficial to generating large optical anisotropy. Therefore, it is urgent to develop suitable methods to improve the optical anisotropy of tetrahedral groups.…”
