Explain the principle of Fluorescence and Phosphorescence. | Analytical Chemistry
Many compounds absorb ultraviolet or visible light and undergo an electronic transition from low electronic energy levels to high electronic, energy levels. This Absorption of light requires 10-15 sec. The instant re-emission of the absorbed energy is called Fluorescence. While delayed re-emission of the absorbed energy is called ...
