The article was appeared in 《Journal of Materials Chemistry C: Materials for Optical and Electronic Devices》. They have made some progress in their research.Reference of Rubidiumchloride The article mentions the following:
Noncentrosym. (NCS) structure is the precondition for second-order nonlinear optical (NLO) materials. In this work, we present a new strategy for constructing NCS structures, whereby mixed alkali metals make a new NCS chalcogenide, (Na3Rb)Hg2Ge2S8, based on the centrosym. (CS) Rb4Hg2Ge2S8. (Na3Rb)Hg2Ge2S8 crystallizes in the polar space group of Pca21, and adopts a filled cristobalite-type structure with a {[HgGeS4]2-}∞ framework formed by the alternating connection of [HgS4] and [GeS4] tetrahedra via corner-sharing and with the mixed alkali metal cations in the cavities of the framework. Structural anal. and theor. calculations suggest that the ordered and alternating arrangement of NLO-active chromophores, [HgS4] and [GeS4] tetrahedra, induced by partial substitution of alkali metals plays an important role in the enhanced second harmonic generation activity. As such, (Na3Rb)Hg2Ge2S8 exhibits strong second harmonic generation response of 1.4 x AgGaS2 at 2090 nm, wide band gap of 2.76 eV and low m.p. of 444 °C. Therefore, this strategy of mixed alkali metals may shed light on structural modification from CS to NCS for new NLO materials. To complete the study, the researchers used Rubidiumchloride (cas: 7791-11-9) .
