Rate of Phosphorescence Formula

Phosphorescence Rate = Phosphorescence Rate Constant*Concentration of Triplet State
Rateph = Kp*[MT]

Why is the rate of fluorescence higher than phosphorescence?

Fluorescence emission occurs at a slower rate. Since the triplet to singlet (or reverse) is a forbidden transition, meaning it is less likely to occur than the singlet-to-singlet transition, the rate of triplet to singlet is typically slower. Therefore, phosphorescence emission requires more time than fluorescence.
