Abstract Liquid‐crystal random lasers (LCRLs) represent a burgeoning field in soft‐matter photonics, holding promise for ushering an era of ultrathin, versatile laser sources. Such encompass multitude remarkable features, including wide‐band tunability, large coherence area and, some cases, multidirectional emission. In this paper, LCRL is developed by doping dye, pyrromethene 597 (PM597), into cholesteric LC, but achieving wide‐range wavelength‐controllable (560–720 nm) bandgap lasing...
Random lasers (RLs), which possess peculiar advantages (e.g., emission and coherence tunable) over traditional with optical resonators, have witnessed rapid development in the past decades. However, it is still a challenge to tune lasing peak of an RL wide range. Here, temperature-dependent Förster resonance energy transfer (FRET) demonstrated pyrromethene 597 (PM597, “donor”) Nile blue (NB, “acceptor”) doped chiral liquid crystals. By changing temperature that drives crystal bandgap shift,...
We successfully fabricated a metal–organic framework-based hydrogel fiber random laser with self-healing function. Impressively, the lasing output can be restored after self-healing, demonstrating potential application in extreme environments.
This article introduces a FRET system and achieves for different laser modes by changing the pump position.
Herein, polychloride ([Cl3]- or/and [Cl5]-) ionic liquids (ILs) were prepared from their imidazolium chloride precursors by the addition of chlorine gas. The highest storage ability Cl2 was found in [Bmim]Cl IL among six chlorides [Rmim]Cl (Rmim = Emim, 1-ethyl-3-methylimidazolium; Bmim, 1-butyl-3-methylimidazolium; Pmim, 1-propyl-3-methylimidazolium; Pnmim, 1-pentyl-3-methylimidazolium; Hmim, 1-hexyl-3-methylimidazolium; and Omim, 1-octyl-3-methylimidazolium). When a mixed [Bmim][Tf2N]...
In this study, the two-dimensional (2D) triangular lattice metallic photonic crystals (PCs) in visible and infrared bands have been utilized to achieve light confinement at Dirac frequency. Distinct from traditional bandgap or total internal reflection cavity modes, unique localization mechanism leads an unusual algebraic decay of state a frequency located beyond any bandgaps. This investigation delves into band structure analysis 2D PCs, specifically focusing on their distinctive features,...
Abstract In contrast to conventional anti‐counterfeiting technologies, which are susceptible decryption and exhibit limited effectiveness, the utilization of light dynamically configure soft materials in a fully reversible programmable manner not only enhances data security but also improves performance. However, achieving precise control over reflection structural colors laser wavelengths within broad dynamic range remains challenge. this study, UV‐responsive helical superstructure is...
