Answer 1

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.
