Elucidating Local Viscosity Using Fluorescence Lifetime Measurements
Certain fluorescent molecules, known as molecular rotors, can be employed to estimate the local (nanoscale) viscosity in microheterogeneous systems by measurement of their fluorescence lifetime. This can be advantageous over the usual fluorescence anisotropy method, as the measurement is simpler and faster to perform. This is demonstrated using the HORIBA Scientific TemPro fluorescence lifetime system to monitor the gelation of silica produced using the sol‐gel technique.
Spectroscopic Ellipsometry Application in Life Science
In recent years, Spectroscopic Ellipsometry application is extended to the life science. In this article, we introduce two examples from this field: Biocompatibility of DLC films and demineralization and remineralization process of tooth surface.
Experimental Assessment of Metal Nanostructures as Effective SERS Substrates
Research in nanoscience has garnered much interest because of the different properties of small structures compared to the respective bulk material.
Photoluminescence of InGaAs/GaAs Quantum Dots
InGaAs/GaAs and InAs/GaAs quantum dots (QDs) have been identified as suitable candidates for various applications in the terahertz range by using their intraband carrier transitions.
The NanoLog Series: A New Generation of Performance
The NanoLog has a reputation as the premier instrument for the exploration of single-walled carbon nanotubes (SWCNTs).
Measuring Silica Nanoparticles via Fluorescence Anisotropy
Silica is currently one of the most important industrial materials, whose nanoparticles are formed via a sol-gel process.
Nanophotonics with Fluorescence Instruments
HORIBA Jobin Yvon’s spectrofluorometers have many applications in nanophotonics research: single-walled carbon nanotubes (SWNTs), quantum dots (QDs), and organic light-emitting diodes (OLEDs). Quantum confinement affects nanomaterials’ photoluminescence: when the semiconducting nanoparticle is smaller than the bulk material’s Bohrexciton radius, the bandgap energy is inversely proportional to the nanoparticle size.
