Long-persistent luminescence (LPL), due to its ability to emit light for a long time without an external power source, is widely used in many areas, such as night indicators, safety signage, and in vivo bioimaging . Recently, organic LPL (OLPL) materials have attracted widespread interest due to their composition without heavy metal elements, the design flexibility of their chemical structure, and the non-stringent processing conditions 3 -5 . The LPL systems that emit visible light are mainly used in scenarios where there is little to no ambient light. The human eye contains different photoreceptor cells that operate under bright and dim lighting conditions, resulting in different spectral sensitivity functions . The sensitivity can be divided into photopic (> 0.6 cd/m 2 ), scotopic (< 10 -3 cd/m 2 ), and mesopic vision in their transition region (Figs. ) . Known as the Purkinje phenomenon, the wavelength sensitivity in scotopic vision, which is mainly mediated by rods, is blueshifted compared to photopic vision, which is mainly mediated by cones . Therefore, the human eye is more sensitive to materials that emit weak light, such as LPL materials, when the emission spectrum fits the sensitivity function of human scotopic vision.
