... luminescence, the Raman scattering is completely obscured. UV gated Raman spectroscopy enables separation of Raman and interfering luminescence signals in both time and spectral domains. In spite of its potential advantages, the technique is not popular in mineralogical sciences, and it is important...

... with it, allows rejection of most of the luminescence signal and maximum collection of the Raman signal ( F ig . 2 ). Time-resolved spectroscopy further allows collection of only the luminescence signal, by opening the detector gate just after the laser pulse. The Raman signal is by then absent, because its...

... is not time-dependent when temperature is maintained. Raman spectra of boron nitride coatings over graphite furnace were obtained up to 2340 K using a pulsed YAG-laser source and gated detection ( Exarhos & Schaaf, 1991 ). Similar systems have been used for high-temperature Raman spectroscopy at high...
