Application Notes: Molecular

Transmission gratings open up many new options for the optical designer. In this tech note, we explore the benefits of transmission gratings over other types.

Efficient charge extraction is crucial for high-efficiency solar cells. Electron and hole extraction layers optimize cell performance. PL spectroscopy, proportional to carrier number, is ideal for comparing extraction layer efficiency.

Olive oil, especially extra virgin, is prized for its quality and purity. However, fraud and adulteration are significant concerns. UV-Vis spectrophotometry is a reliable technique for assessing olive oil quality by quantifying key compounds. An Edinburgh Instruments DS5 Spectrophotometer is used to evaluate olive oil quality and detect adulteration.

Photon upconversion converts low-energy photons to higher-energy photons. UCNPs, composed of rare-earth elements, can convert near-infrared light to visible or UV light. They have potential applications in solar energy and biomedicine. Understanding their luminescence properties is crucial for optimization. FS5 Spectrofluorometer was used for comprehensive upconversion characterization.

High structural selectivity of Raman, with spectral & spatial resolution & non-destructive nature of Raman make it ideal as a standard characterization tool in the growing field of graphene.
