• #### A$_2$P$_2$S$_6$ (A = Ba and Pb): a good platform to study the polymorph effect and lone pair effect to form an acentric structure ﻿

(The Royal Society of Chemistry, 2022-05-14)
Three ternary thiophosphates α-Ba$_2$P$_2$S$_6$, β-Ba$_2$P$_2$S$_6$, and Pb$_2$P$_2$_S$_6$ were synthesized via a high temperature salt flux method or an I2 transport reaction. β-Ba$_2$P$_2$S$_6$ and Pb$_2$P$_2$S$_6$ were ...
• #### Applying band gap engineering to tune the linear optical and nonlinear optical properties of noncentrosymmetric chalcogenides $La_4Ge_3Se_X S_{12- x} (x = 0, 2, 4, 6, 8, 10)$ ﻿

(Royal Society of Chemistry, 2021-09-10)
$La_4Ge_3S_{12}$ was structurally characterized in 1974 without any optical or nonlinear optical properties reported. Herein we report that the acentric crystal structure of $La_4Ge_3S_{12}$ has been confirmed by single-crystal ...
• #### Revisiting thiophosphate $Pb_3P_2S_8$: A multifunctional material combining a nonlinear optical response and photocurrent response ﻿

(Royal Society of Chemistry, 2021-09-30)
$Pb_3P_2S_8$ was structurally characterized three decades ago with a second harmonic generation response. In this work, $Pb_3P_2S_8$ was revisited to investigate its electronic structure via DFT calculations and optical ...
