Title: Plastic Films, Fabrics, Nano Particles, and Butterfly Wings: Novel, “Outside the Box”, Uses For UV/Vis/NIR Integrating Spheres

Duration: 1 hour

Available On Demand

 

Summary

This webcast will consist of two parts. Part 1 will start off with a basic introduction to UV/Vis/NIR integrating spheres. We will then consider samples, such as plastic films and colored Spectralon®, that illustrate how sphere diameter can impact spectral accuracy in both reflectance and scatter transmission measurements. This section will conclude with a look at how sample surface texture and sample placement against the sphere’s port, can result in unusual artifacts in the spectra.

Part 2 will discuss two novel integrating sphere applications within the rapidly growing technology field of nanomaterials. Carbon nanotubes constitute a large arena of products where UV/Vis/NIR spectroscopy, employing an integrating sphere, is functional in both research and quality control. The webcast will conclude with a detailed look at the UV/Vis/NIR spectroscopy of butterfly wings. The colors on most butterfly wings do not arise from either dyes or pigments, but from nanostructures that physically diffract, rather than absorb light. As such, they represent an interesting platform to investigate the potential for spectroscopic materials characterization of nanostructures attached to surfaces.
