Focus issue introduction: Persistent phosphors
Full text: Download
Abstract
Persistent phosphors can emit light long after the excitation has ended. The field of persistent luminescence has strongly matured during the past decade, with considerable progress having been made in synthesis and characterization methods, the understanding of trapping and de-trapping mechanisms, and the application of these materials. This focus issue “Persistent Phosphors,” within the April 2012 issue of Optical Materials Express, features papers presented at the first International Workshop on Persistent Phosphors (Phosphoros 2011) held in Gent, Belgium.
