Photoluminescence spectrometers

Photoluminescence spectrometry involves exciting the electrons in a material by exposing it to a light source, typically a laser or UV light. As the excited electrons return to their ground state, they emit light which is collected and analyzed using a spectrometer. The intensity and wavelength of the emitted light provide information about the material's electronic structure, energy levels, and defects. This technique is widely used to characterize semiconductors, organic compounds, and nanomaterials for their optical and electronic properties.
