This paper first reports random laser action in dye-doped ferromagnetic nematic liquid crystals, which act as a randomly distributed cavity. The random laser intensity of the ferromagnetic nematic liquid crystals can be controlled by a weak magnetic field (∼1 mT). Moreover, the magnetic switching of random laser is attributed to the direction and polarization dependent emission of light in the ferromagnetic nematic liquid crystals in an external magnetic field.

“…This part was dissolved in acetone, and the concentrations of their diluted solutions were spectrophotometrically determined. [12,18] The absorption spectra of the dye solutions were scanned on a PerkinElmer Lambda 900 UV-Vis-NIR double-beam spectrophotometer. The sample holder was a quartz cell with a path length of 10 mm.…”

During the recent years, liquid crystals (LCs) have much attention owing to their wide range of possible application and structural properties in electronics and optics. In this study, two different azo structured dyes (Disperse Yellow 3 and 7) and their mixture were separately doped to each of two different nematic LCs (E8 and E63). Their solubilities (except dye mixture), order parameters, textures and phase transition temperatures were determined. Single-walled nanotubes and fullerene C60 in a small amount were separately added to each of these solutions, and the experiments were repeated at the final stage analogously except solubilities. The solubilities of dyes in the LC E63 were lower than those of E8. The highest order parameter value was attained with Yellow 7 dye in E63 nematic host.

“…Generally, various kinds of guest-host systems are used to enhance their optical and electro-optical properties and improve the performance of optoelectronic devices [4][5][6][7][8]. The linear and nonlinear optical properties of the host material can be affected considerably, by doping with a small amount of dye [9][10][11][12][13]. From the standpoint of optical properties, doping of liquid crystals by appropriately dissolved concentrations and types of dyes clearly deserves special attention [12][13][14].…”
