Shedding light on intrinsic characteristics and optical properties of novel selenite and tellurite crystals ZrSe₂O₆, HfSe₂O₆ and HfTe₃O₈

Abstract

The selenite and tellurite compounds have garnered plenty of attention in both fundamental and applied chemistry. Se4+ and Te4+ cations possess lone pair electrons, which changes coordination environments and performance...

A UV non-hydrogen pure selenite nonlinear optical material for achieving balanced properties through framework-optimized structural transformation

“…In Fig. 8b, 30,[32][33][34] we summarize the birefringence of currently reported UV pure selenite compounds. As shown, the compound NaLu(SeO 3 ) 2 exhibits the largest birefringence reported to date, indicating that NaLu(SeO 3 ) 2 could serve as a potential material for UV birefringence applications.…”

“…[25][26][27][28] Researchers have undertaken extensive efforts to explore systems within selenite compounds suitable for use as UV NLO materials. 29,30 (a) Fluoride selenites. The first UV selenite NLO material, Y 3 F(SeO 3 ) 4 , exhibits a wide band gap, large SHG response, The concept of enhancing non-centrosymmetric (NCS) oxides for UV nonlinear optical (NLO) applications through framework-optimized structural transformation is a major leap in materials science.…”

“…25–28 Researchers have undertaken extensive efforts to explore systems within selenite compounds suitable for use as UV NLO materials. 29,30 (a) Fluoride selenites. The first UV selenite NLO material, Y 3 F(SeO 3 ) 4 , exhibits a wide band gap, large SHG response, and appropriate birefringence, demonstrating the potential of fluoride selenites as UV NLO materials.…”
