Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the … WebChong Principles of Spectroscopy - UGPTI Webincluding fluorescence and dual phosphorescence. Single-crystal analyses and theoretical calculations suggest dual phosphorescence derives from local excitation and charge-transfer component.
