Optically stimulated luminescence and signal stability of magnesium borate doped with gadolinium-lithium
Abstract
This paper explores the effects of codopance with lithium using the gadolinium metal from the lanthanide series. The embodied work include an analysis on a material's ability to capture and hold a 'signal' — or a radio-receptive induced excited state — over time. Recombination centers of optically stimulated luminescence (OSL) and thermoluminescence (TL) will be discussed in some detail when considering the stability of the material. The gadolinium-lithium material is of interest because of its instability; however, its codopant participation with lithium-lanthanide impurities make it a viable candidate for illuminating a strong signal [1]. This investigation will provide a calibration approach to explore and identify the dopant conditions to synthesize an OSL material that is both bright and stable. Stability is used in a variety of different contexts when it comes to OSL and TL measurements. The actual term, however, is attributed to the material's ability to hold and maintain a signal over certain constraints. Since the material has immediate applications in OSL since it is a bright material, the focus of this exploration will be upon the stabilization of the doped material in regards to OSL.
