Scintillation and luminescent properties of undoped and Ce3+ doped Y2SiO5 and Lu2SiO5 single crystalline films grown by LPE method

Near UV–blue emission from Ce doped Y2SiO5 phosphor

“…In the PL spectra which shows linear response with concentration up to 1.5 mol% of Ce 3 þ after that concentration quenching occurs (Fig. 4b) and the luminescence intensity decreases with increasing the Ce 3 þ concentration [39,40].…”

Thermoluminescent Properties of Cerium-Doped Lu2SO5 and Y2SiO5 Single Crystalline Films Scintillators Grown from PbO-B2O3 and Bi2O3 Fluxes

“…The emission bands peaked at 374/365 nm correspond to the 3 P1→ 1 S0 transitions of Pb 2+ ions in Y1/Lu1 sites of YSO and LSO hosts with seven oxygen ligands [7,16] (further noted as Pb1 centers, respectively). The nature of the 434/446 nm emission bands (Pb2 centers) is still not clear, and can been interpreted as: (i) the emission of the excitons localized around Pb 2+ based centers [6][7][8]; (ii) the luminescence of Pb 2+ ions inY1/Lu1 sites of the X2 structure with seven oxygen ligands or in Y2/Lu2 sites of the X1 structure with six oxygen ligands [15,22]. The CL spectra of nominally undoped YSO and LSO SCFs grown from PbO based flux are shown in Figure 2a,b, curves 2, respectively.…”

“…Due to their high-density, LSO with rare-earth dopants are competitive to other scintillating materials, such as LuAlO 3 (LuAP) perovskite or Lu 3 Al 5 O 12 (LuAG) or Gd 3 Ga 5 O 12 (GGG) garnets for X-ray imaging with submicron resolution [2,3]. Specifically, during the last few years, Tb 3+ , Ce 3+ , and Ce 3+ -Tb 3+ single crystalline films (SCFs) of LSO and YSO orthosilicates were developed using the liquid phase epitaxy (LPE) method [4][5][6][7][8] for application as scintillating screens in microimaging detectors with special resolution even in the submicron range [9,10].…”

OSL dosimetric properties of cerium doped lutetium orthosilicates

“…For commercial applications single crystals of LSO:Ce grown by Czochralski method are used. Recently several studies have been done on luminescent properties of single crystalline films prepared using Liquid Phase Epitaxy (Zorenko et al 2012). As was suggested by Zorenko et.…”
