The quest for new thermoluminescence and optically stimulated luminescence materials: Needs, strategies and pitfalls

The quest for new materials for thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetry continues to be a central line of research in luminescence dosimetry, occupying many groups and investigators, and is the topic of many publications. Nevertheless, it has also been a research area with many pitfalls, slow advances in...

Persistent luminescence excitation spectroscopy of BaAl₂O₄:Eu²⁺,Dy³⁺

BaAl₂O₄:Eu²⁺,Dy³⁺ is related, both by structure and luminescence, to one of the best persistent luminescent phosphors, SrAl₂O₄:Eu²⁺,Dy³⁺. At room temperature (RT), the green persistent emission of BaAl₂O₄:Eu²⁺,Dy<sup>3+<...

Synthesis optimization and charge carrier transfer mechanism in LiLuSiO₄:Ce, Tm storage phosphor

LiLuSiO₄:Ce and LiLuSiO₄:Ce, Tm show very efficient charge carrier storage properties upon beta irradiation after samples have received treatment in vacuum. They outperform the commercial storage phosphor BaFBr(I):Eu²⁺ in many aspects. The influence of the synthesis conditions, Ce and Tm concentration,...
