![]() Photoluminescence used in Fluorescence spectroscopy can provide two results: Fluorescence and Phosphorescence. A wide range of excitation wavelengths is possible, from the UV to NIR, allowing control of the penetration depth into the material, and thus, control of the volume sampled. Combined Raman-PL systems allow confocal mapping capabilities with sub-micron spatial resolution. These products are also making a major contribution to the development of nanomaterials, semiconductors, photovoltaics / solar cells.īy combining Raman analysis with PL detection, it is possible to characterize both the vibrational and electronic properties of materials on a single bench top platform. ![]() Our PL optimized series of spectrophotometers are used in Fluorescence Spectrometers, Raman Spectrometers and our Custom Optical Solution Systems. The emission of light or luminescence through this process is photoluminescence, PL. The photo-excitation causes the material to jump to a higher electronic state, and will then release energy, (photons) as it relaxes and returns to back to a lower energy level. In essence, light is directed onto a sample, where it is absorbed and where a process called photo-excitation can occur. ![]() ![]() It is a non-contact, nondestructive method of probing materials. Photoluminescence spectroscopy, often referred to as PL, is when light energy, or photons, stimulate the emission of a photon from any matter. ![]()
