Question

what is fluorescence​

Answer 1

$\huge\underline\mathfrak\blue{Answer}$

Fluorescence, a type of luminescence, occurs in gas, liquid or solid chemical systems. Fluorescence is brought about by absorption of photons in the singlet ground state promoted to a singlet excited state. The spin of the electron is still paired with the ground state electron, unlike phosphorescence.
