Time-resolved spectroscopy of complex scintillators Al2BeO4, Be2SiO4 and Al2Be3Si6O18

The present work is devoted to investigations of the luminescence properties of aluminum-, beryllium- and silicon-containing complex wide gap oxides in energy range 2.5–32 eV at temperature 10–300 K using time-resolved VUV-spectroscopy and ionluminescence methods. It has been shown that all studied crystals possess intrinsic luminescence in the UV-region of spectrum. Phenomenon of electron excitations multiplication has been found in excitation spectra of intrinsic luminescence. The difference and typical features of photoluminescence and ionluminescence (luminescence excited by accelerated particle beam) are discussed.
