Interpretation Introduction
Interpretation:
The reason for some absorbing compounds being fluoresce but others are not is to be stated.
Concept introduction:
Fluorescence is a term used to define the members of the luminescence family. In the luminescence family, the molecules of a substance can produce their own light with the help for electronically excited states which can be formed by chemical,physical or mechanical mechanism.
