Energy Relaxation in LSO and LGSO Crystals Studied in the VUV Range

Thermally stimulated luminescence of undoped and Ce3+-doped Gd2SiO5 and (Lu,Gd)2SiO5 single crystals

“…Besides GSO, mixed Lu 2x Gd 2 À 2x SiO 5 crystals (with x varying from 0 to 1), which have even more attractive scintillation characteristics, were also prepared and studied (see, e.g., Refs. [16,[28][29][30][31][32][33][34][35] and references therein). These crystals were denoted also as (Lu,Gd) 2 SiO 5 :Ce [30] (LGSO:Ce) crystals.…”

“…The emission bands of the intrinsic, Ce 3 þ -, Tb 3 þ -related and Eu 3 þ -related luminescence centers are located in the 2.5-3.2 eV and 1.7-2.1 eV energy ranges, respectively (see, e.g., Refs. [20,32,39,46,[48][49][50][51][52][53][54][55][56][57]), i.e. they are well separated.…”
