CLAVI pulsed cathodoluminescence spectroscope

Composite Nd:YAG/Cr4+:YAG transparent ceramics for thin disk lasers

“…With increasing Cr content in ceramics, the concentration of Cr 4+ also increases but the ratio N 1 /N Cr decreases and does not exceed 0.5% suggesting the presence of main part of Cr in trivalent state. Trivalent Cr ions appear well in cathodoluminescence spectrum [18] as the red band (Fig. 2) containing R line of Cr 3+ at 689 nm and N line of Cr 3+ -Cr 3+ pairs.…”

Luminescence and superradiance in electron-beam-excited AlxGa1−x N

“…The emission spectra were examined using a pulsed spectrograph. 31 The time-integral luminescence spectrum in the range of wavelengths from 220 to 900 nm was registered with the help of two multi-channel photodetectors from the side of irradiated surface. Stability of the luminescence coming from one and the same sample was better than 90%, and the error in measuring the wavelength was 60.75 nm.…”

Luminescence and absorption of divalent ytterbium ion in yttrium-aluminum garnet ceramics

“…No additional reflections were revealed for the samples of annealed ceramics; how ever, the lattice parameter a reduced to 1.2000 ± 0.0001 nm (a = 1.2006 ± 0.0001 nm in unannealed ceramics). 2 7/2,5/2 F Pulse cathodoluminescence (PCL) was excited and investigated on a KLAVI setup [22]. The samples were not subjected to any special treatment before the analysis.…”
