Liquid crystal self-assembly of upconversion nanorods enriched by depletion forces for mesostructured material preparation
Yong Xie, Yuanyuan Li, Guoqing Wei +4
Monodisperse rod-like colloidal particles are known for spontaneously forming both nematic and smectic liquid crystal phases, but their self-assembly was typically exploited from t…
Tuning and Switching a Plasmonic Quantum Dot Sandwich in a Nematic Line Defect
Haridas Mundoor, Ghadah. H. Sheetah, Sungoh Park +3
We study the quantum-mechanical effects arising in a single semiconductor core/shell quantum dot controllably sandwiched between two plasmonic nanorods. Control over the position a…
Plasmon-Exciton Interactions Probed Using Spatial Coentrapment of Nanoparticles by Topological Singularities
P. J. Ackerman, Haridas Mundoor, I. I. Smalyukh +1
We study plasmon-exciton interaction by using topological singularities to spatially confine, selectively deliver, cotrap and optically probe colloidal semiconductor and plasmonic…
Electric Switching of Fluorescence Decay in Gold-Silica-Dye Nematic Nanocolloids Mediated by Surface Plasmons
Li Jiang, Haridas Mundoor, Qingkun Liu +1
Tunable composite materials with interesting physical behavior can be designed through integrating unique optical properties of solid nanostructures with the facile responses of so…
Imaging of director fields in liquid crystals using stimulated Raman scattering microscopy
Taewoo Lee, Haridas Mundoor, Derek G. Gann +2
We demonstrate an approach for background-free three-dimensional imaging of director fields in liquid crystals using stimulated Raman scattering microscopy. This imaging technique…
Mesostructured composite materials with electrically tunable upconversion properties
Haridas Mundoor, Ivan I Smalyukh
A promising approach of designing mesostructured materials with novel physical behavior is to combine unique optical and electronic properties of solid nanoparticles with long-rang…
