WebWe report herein a triphenodioxazine dye, which is highly dichroic and luminescent in liquid crystal (LC). The dye shows remarkable polarization dependence resulting from its high … Web7 de out. de 2024 · In terms of polarization sensitivity, DPA-crystal based photodetectors exhibit a linear dichroic ratio up to ≈1.9. Theoretical calculations confirm that intrinsic linear dichroism, originated from the anisotropic in-plane crystal structure, is responsible for the polarization sensitivity of DPA crystals.
Dichroic ratio and order parameters of some sudan dyes
WebIdeally, the dichroic ratio should be as high as possible. Of all the negative dichroic dyes tested, the tetrasubstituted 1,8-bis- (heptylbenzoylamino)-4,5-bis-(heptylbenzoyloxy)anthraquinone (Fig 9) at 1 wt % in E7 was found to be the most promising for the LCPDI. Unfortunately ... WebFrom these distributions, we calculated dichroic absorption values, as well as order parameters. We established a connection between the dichroic ratio R ATR , which is measured in IR-ATR setups, with the dichroic ratio D and the order parameter S zz . The calculated values compare well with experimental results for the fluid phase. phlebotomy math practice questions
