Energy Transfer and Defects Study in ${\rm Ce}^{3+}$ , ${\rm Pr}^{3+}$ Co-doped ${\rm Lu}_{2}{\rm Si}_{2}{{\rm O}_7}$ Crystal

Lu2Si2O7 (LPS) single crystals doped with 0.05%Ce and co-doped with 0.05%Ce, 0.05%Pr were grown by floating zone method. The segregation coefficients of Pr and Ce in LPS host were estimated through ICP-OES method. The VUV-UV excitation and emission spectra at 150 K, X-ray excited luminescence, fluorescence decay time of Ce3+ emission at room temperature and thermally stimulated luminescence (TSL) ...
