Unveiling of UV intrinsic luminescence in (Lu,Y)2SiO5:Ce3+ single crystals
(2024) In Optical Materials 152.- Abstract
Intrinsic luminescence in Ce-doped (Lu,Y)2SiO5 (or LYSO:Ce) single crystals have been studied by means of excitation luminescence spectroscopy in the vacuum ultraviolet energy range under synchrotron radiation. A previously unreported luminescence band with emission at 250 nm has been discovered as well as its thermal behavior was described in the temperature range 10–120 K. The excitation spectra as well as time-resolved properties of this band suggest that this emission corresponds either to the singlet component of self-trapped exciton or to a self-trapped exciton in the lutetium sublattice of LYSO single crystals.
