Persistent luminescence, commonly called afterglow, is characterised by long-lasting visible emission over several hours after ultraviolet excitation. This finds wide applications in glow-in-the-dark signage and in-vivo imaging for disease diagnosis and treatment. However, biological tissue allows transmission of near-infrared (NIR) light shorter than 1400 nm due to absorption by water and lipids. The majority of bioimaging applications utilises the 700 nm-950 nm window.
