Shimadzu Scientific Instruments publishes poster on 'The spectroscopic analysis of carbon nanotube (CNT) composite materials by diffuse transmission and diffuse reflectance in the UV-Vis-NIR regions'
Carbon nanotubes (CNT) are an important class of materials for the development of novel electronic and optical devices.
There is also interest in exploiting their intrinsic optical properties as a new class of nanomaterials for drug delivery and cancer therapy.
While there are a number of ways to synthesise or create CNT (eg, chemical vapour deposition, carbon arc discharge, and pulsed-lased vaporisation), they are all structurally related to graphitic carbon.
Recent attempts have been made to develop methods to characterise CNT as composite films rather than the traditional solution-based measurements.
At a fundamental level, the build-up or thickness of these composite films may require that several spectroscopic measurement techniques be applied.
This poster summarises efforts to compare both diffuse transmission and diffuse reflectance measurements with the UV-3600 UV-Vis-NIR spectrophotometer.
The UV-3600 delivers high-resolution spectroscopic analysis (185nm-3300nm), virtually eliminating the low levels of sensitivity normally present in the NIR light range.
With three detectors, the UV-3600 ensures high-sensitivity throughout the range.
