New Combined Raman/PL Microscope For Nanomaterials Characterisation

24 Jan 2006

HORIBA Jobin Yvon is pleased to announce the launch of a new LabRAM Raman/PL microscope configuration designed to provide everything needed for molecular characterisation of nanomaterials on one bench top system.

Typical nanomaterials, such as carbon nanotubes (CNT), boron nitride, SAM and LB films, polymers, and semiconductors can be routinely analysed with Raman microscopy to provide information on composition and purity, CNT chirality and radius, stress/strain, crystallinity, homogeneity. However, photoluminescence (PL) of many of these materials is equally important giving an insight into their electronic structure. With the nanomaterials LabRAM both Raman and PL can be quickly acquired from the same point on the sample, offering fuller characterisation on one system.

The wavelength range over which PL occurs is extremely broad, so the nanomaterials LabRAM is equipped with a high performance dual detection system sensitive from 200 nm to 2.2 ìm. Whether for boron nitride signals in the UV/blue, through to CNT and semiconductor emission in the near infra-red, the LabRAM ensures consistent high through put and sensitivity across the range.

Raman experiments can also exploit this wide wavelength range - a choice of laser excitation from UV to IR ensures that scattering efficiency, spot size, penetration depth, resonance, and fluorescence minimisation can all be optimised for a given sample to ensure that as much useful information can be acquired in as short a time as possible.

With the unrivalled sub-micron spatial resolution offered by the nanomaterials LabRAM, Raman/PL mapped images illustrating sample heterogeneity, chemical distribution, and stress/strain variation are quickly and easily acquired. A nanopositioning XYZ stage ensures that even the smallest of features is not lost.

The nanomaterials LabRAM builds on the success of the award winning LabRAM family, but with a carefully defined "nano" configuration is sure to light up YOUR materials research.
