Diffuse Reflectance Spectroscopy (DRS)
A UV-Vis method for opaque or light-scattering solids such as powders. Light reflected from the surface in all directions is used to assess absorption, electronic structure, and optical bandgap of semiconducting materials.
Sample requirements
- State the nature of the sample (for example hazardous, volatile, or explosive).
- Minimum sample quantity: 0.2 g, in an Eppendorf tube placed in a ziplock bag.
- Only solid, powder, or thin film samples are acceptable.
