Luminescent emission in the form of phosphorescence commonly occurs in daily life as a result of a quantum mechanically small transition probability. A luminescent emission lifetime can last from microseconds to several hours. Popularly known for its use in glow-in-the-dark products and as emergency sign illuminants in public buildings, it is also a practical method for information storage, including stamp detection and verification. While easy and cost-effective fabrication methods presently exist to engineer phosphorescence systems using organic emitters, achieving visible organic phosphorescence under ambient conditions in lab for industrial translation is challenging.
