Application Note: Kinetics of Persistent Luminescence Phosphors
Author: Georgios Arnaoutakis
Saturday, July 1, 2017
Persistent luminescence, or commonly called afterglow, is
characterized by long-lasting visible emission over several
hours after ultraviolet excitation. This finds wide application
in glow-in-the-dark signage and in-vivo imaging for disease
diagnosis and treatment. Biological tissue, however, allows
transmission of near-infrared (NIR) light shorter than 1400 nm
due to absorption by water and lipids. The majority of bio-imaging
applications utilizes the 700 nm-950 nm window.
