Renishaw’s Invia Micro Raman and PL spectroscopy system is currently equipped with a He-Cd (325 nm) and Nd-YaG ( 633 nm) lasers. The 633 nm laser ( red) is primarily used to accurately identify the phase of materials with a resolution of 1 micron ( under confocal mode). This technique to used study phase and defect in bulk crystals, as well as nano particle dispersions. The same set of analysis can be performed by the 325 nm laser( UV). In addition, the high energy UV laser ( 3.8 eV) also enables us to perform PL spectroscopy to study. PL spectroscopy aids in the determination of energy band gap and defect states in the energy band of semiconducting specimens. This tool also assists in analyzing quantum confinement effects on nanomaterials synthesized at the CVD lab. With this instrument we also have the capability to add two more lasers of different wavelengths in the future without any further modifications.
