What is Nanomaterials?

Nanomaterials is a major field of advance material research. Over the last three decades, nanomaterials, especially, polymer and silicon based materials, have experienced tremendous rise in interest due to the extraordinary ability to manipulate their structure and composition at the atom level, leading to the development of novel materials with unique properties that were not available before. Today, nanomaterials are used over a wide range of applications including automotive, semiconductors, energy storage and biomedical, to name just few examples.

HORIBA offers a large choice of innovative technologies such as Surface Enhanced Raman Spectroscopy [SERS], steady state and lifetime fluorescence, photoluminescence, ellipsometry and particle size analysis to support a wide range of nanomaterials applications.

We have performed a complete Raman polarized study of a single GaN nanowire using a confocal microscope together with a high resolution stage. The high spatial resolution of our Raman confocal instrument together with a piezoelectric stage demonstrates unambiguously the possibility to image the optical properties of nano-objects with a resolution better than 200 nm keeping the fill advantage of the polarization control under a confocal microscope.
PLQY in NIR with Fluorolog-QM and K-Sphere
The Fluorolog-QM fluorescence spectrometer with an integrating sphere option is an excellent choice for PLQY measurements in NIR. The K-Sphere is very convenient and easy to use, as it couples directly to the sample compartment optics and allows a use of external light sources, such as DPSS lasers, which can be attached to the front of the sample compartment. The sphere has holders for cuvettes, slides and powders that can be easily interchanged. The results demonstrate very good reproducibility and precision for NIR PLQY measurements spanning almost two orders of magnitude. Based on multiple measurements, the demonstrated PLQY standard deviations range from 1.3% for high QY value (77%) to 6.4% for the QY below 1%.
