Horiba Jobin Yvon has introduced the LabRAM Raman/PL microscope configuration designed to provide everything needed for molecular characterisation of nanomaterials on one benchtop 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 and 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 2.2µm. Whether for boron nitride signals in the UV/blue, through to CNT and semiconductor emission in the near infrared, the LabRAM ensures consistent high throughput 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.
