Low absorption liquid crystals for mid-wave infrared applications.
A partially fluorinated terphenyl liquid crystal with low absorption in both mid-wave infrared (MWIR) and near IR regions is developed and its properties evaluated. This compound exhibits a nematic phase (although only about 2 °C), reasonably high birefringence (Δn~0.2), low visco-elastic coefficient, and modest dielectric anisotropy (Δε = -2.7). This compound serves as an important first examp...
متن کاملNanoplasmonic mid-infrared biosensor for in vitro protein secondary structure detection
Plasmonic nanoantennas offer new applications in mid-Infrared absorption spectroscopy with ultrasensitive detection of chemical and structural signatures of biomolecules, including proteins, due to their strong resonant near-fields. The amide I fingerprint of a protein contains conformational information that is greatly important for understanding its function in health and disease. Here, we in...
متن کاملNanoplasmonic enhancement of single-molecule fluorescence
We demonstrate that the fluorescence rate from a single molecule with near-unity quantum yield can be enhanced by a factor of ≈10 by use of a single laser-irradiated noble metal nanoparticle. The increased fluorescence rate is primarily the result of the local field enhancement. However, at particle–molecule distances shorter than 2 nm, nonradiative decay of the excited molecule due to energy t...
متن کاملNanoplasmonic renormalization and enhancement of Coulomb interactions
In this paper, we propose a general and powerful theory of the plasmonic enhancement of the many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. We illustrate this theory by computing the dressed interaction explicitly for an important example of metal–dielectric nanoshells which exhibits a rich resonant behavior in magnitude and phase. This ...
متن کاملA highly efficient CMOS nanoplasmonic crystal enhanced slow-wave thermal emitter improves infrared gas-sensing devices
The application of plasmonics to thermal emitters is generally assisted by absorptive losses in the metal because Kirchhoff's law prescribes that only good absorbers make good thermal emitters. Based on a designed plasmonic crystal and exploiting a slow-wave lattice resonance and spontaneous thermal plasmon emission, we engineer a tungsten-based thermal emitter, fabricated in an industrial CMOS...
