Horiba To Hold Webinar On Defects And Impurities

Using Raman spectroscopy and photoluminescence to detect disruption of long-range translational symmetry in crystals

Horiba Scientific, a Raman Spectroscopy company, is offering a free webinar focusing on how the disruption of long-range translational symmetry in crystals by defects or impurities affects the phonon spectrum.

The webinar, entitled, ‘Raman Spectroscopy and Photoluminescence of Defects and Impurities in Crystals’ will be on Thursday, April 27th, at 10:00 AM PDT/1:00 PM EDT.

It will be moderated by Laura Bush, editorial director of Spectroscopy. Content will be provided by David Tuschel, manager of raman applications for Horiba Scientific.

The webinar is targeted at materials scientists and spectroscopists who work with solid-state materials. Attendees will be shown the sensitivity of Raman spectroscopy and photoluminescence to the presence of defects and impurities in crystals, and how these defects or impurities affect the phonon spectrum, as seen by the shifting and broadening of Raman bands.

Impurities in a crystal can be detected through photoluminescence. This is particularly true for the presence of transition metal and lanthanide impurities in an otherwise transparent host crystal.
