Question

Compounds with fluorescence and/or phosphorescence, what can do both?

Answer 1

Fluorescence and phosphorescence are related to the emission of light by certain compounds. Fluorescence occurs when a compound absorbs light and emits light of a lower energy, while phosphorescence involves the slow release of stored excitation energy as visible light. Phosphorescence generally takes longer because the decay from metastable states is slower.

Step-by-step explanation:

Fluorescence is a natural phenomenon where certain compounds absorb light of a specific energy and emit light of a lower energy. Phosphorescence, on the other hand, occurs when atoms or molecules are excited to metastable states and slowly release stored excitation energy as visible light.

While both fluorescence and phosphorescence involve the emission of light, phosphorescence typically takes longer because the decay from metastable states occurs more slowly.
