Abstract

We have grown single crystals of a Li6Gd(BO3)3:Ce (LGBO:Ce) scintillation phosphor modified with sodium. The thermostimulated luminescence curves of the crystals of Li6−x NaxGd(BO3)3:Ce (0.1<x<0.3) exhibit, in addition to the peak at 425 K observed for the initial compound, a new intense peak at 362 K. The total thermoluminescence yield from the modified crystals is more than 20 times that of the initial (nonmodified) LGBO:Ce with a close Ce activator content (0.012–0.019 wt %). The energy accumulation in the new material is explained by the formation of hole traps of the % MathType!MTEF!2!1!+-% feaafiart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr% 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9% vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x% fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaacbaGaa8Nvam% aaBaaaleaacaWFmbGaa8xAamaaCaaameqabaGaa83kaaaaaSqabaaa% aa!3995!\[V_{Li^ + } \] type filled in the field of the % MathType!MTEF!2!1!+-% feaafiart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr% 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9% vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x% fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaacbaGaa8Ntai% aa-fgadaqhaaWcbaGaa83raiaa-rgadaahaaadbeqaaiaa-ndacaWF% RaaaaaWcbaGaa83kaaaakiabgUcaRiaa-zfadaWgaaWcbaGaa83tam% aaCaaameqabaGaa8Nmaiaa-1caaaaaleqaaaaa!401F!\[Na_{Gd^{3 + } }^ + + V_{O^{2 - } } \] growth defect favoring the spatial separation of charge carriers.
