Journal ArticleDOI
Distance-dependent metal enhanced fluorescence by flowerlike silver nanostructures fabricated in liquid crystalline phase
Ying Zhang,Chengliang Yang,Guiyang Zhang,Zenghui Peng,Lishuang Yao,Wang Qidong,Zhaoliang Cao,Quanquan Mu,Li Xuan +8 more
TL;DR: In this article, the distance between silver nanostructures and fluorophore was controlled by the well-established layer-by-layer (LbL) technique constructing alternate layers of poly (allylamine hydrochloride) (PAH) and poly (sodium 4-styrenesulfonate) (PSS).
Journal ArticleDOI
Electrooptical properties of new type fluorinated phenyl-tolane isothiocyanate liquid crystal compounds
Zenghui Peng,Wang Qidong,Yonggang Liu,Quanquan Mu,Zhaoliang Cao,Xu Huanyu,Zhang Peiguang,Chengliang Yang,Lishuang Yao,Li Xuan,Zhang Zhiyong +10 more
TL;DR: In this article, a series of 4-alkyl-phenyl and 2-6-difluorotolane isothiocyanate liquid crystal (LC) compounds were synthesized, and their phase transitions and electrooptical properties were investigated.
Journal ArticleDOI
Enhanced birefringence for metallic nanoparticle doped liquid crystals
TL;DR: In this article, the scattering influence for metallic nanoparticles was investigated theoretically based on the Maxwell-Garnett effective medium theory, and improved birefringence was obtained in the whole visible wavelength range.
Journal ArticleDOI
Super-broadband geometric phase devices based on circular polarization converter with mirror symmetry
TL;DR: In this article, a simple implementation to obtain super-broadband geometric phase devices (GPDs) by means of circular polarization converter (CPC) with mirror symmetry was proposed.
Journal ArticleDOI
Twisting Structures in Liquid Crystal Polarization Gratings and Lenses
TL;DR: In this paper, the authors divide twisting structures into two main types, namely, multi-layer twisting structures with phase compensation and twisting structures forming Bragg diffraction, and they found that multilayer twisting structure LCPGs and LCPLs presented a broader bandwidth and a wider view angle by phase compensation.
