Answer:
D. / 4 - Phosphorescents
Explanation:
Phosphorescence occurs when light is absorved by a material, and when the material is in the dark we can see how radiation is emitted from the object, in the form of light. Phosphorescent materials are called phosphorescents.
Facts/notes:
- This does not occur immediately
- It occurs from a longer time than fluorescence (because electrons take longer to slow down their movement)
- It is a photoluminescence
- Remember that bioluminescence is not strictly related to phosphorescence. It's a type chemiluminescence.
- For a more detalied understaning you should read about excitation, types of excitation and how this causes/affects phosphorescence.
