Temperature dependent persistent luminescence: Evaluating the optimum working temperature

Abstract Development of persistent luminescent materials has drawn continuous attention in recent years in view of their potential applications in the fields of security night-vision signage, in vivo bio-imaging and optical data storage. Currently, the normative evaluation of a new persistent lumine...
