摘要: We report the photo-isomerization and electro-isomerization effects in azobenzenes-doped polymer-dispersed liquid crystals during the switching of the liquid crystal (LC) device between transparent (cis-isomers dominant) and scattering states (trans-isomers dominant). The isothermal phase transition, which is a result of the illumination of UV light and the application of DC voltage, was the main mechanism to switch the LC device between transparency, scattering, and gray scales. This study discusses in detail the variations in the population of cis-isomers as functions of the period and the amplitude of the applied DC voltage. 其他題名: Opt Express 出版者: United States 出版日期: 2014-02-24 出處: Optics express, 2014-02, Vol.22 (4), p.4404 資源來源: Optica Publishing Group Journals 識別號: ISSN: 1094-4087 識別號: EISSN: 1094-4087 識別號: DOI: 10.1364/OE.22.004404 識別號: PMID: 24663763
