Application Note: Kinetics of Persistent Luminescence Phosphors

Persistent luminescence, commonly called afterglow, is long-lasting visible emission over several hours after ultraviolet excitation. It has many applications; ranging from glow-in-the-dark signage to in-vivo imaging for disease diagnosis and treatment. In this application note, the persistent luminescence kinetics of a doped strontium aluminate phosphor are characterised using the FLS1000 Photoluminescence spectrometer
