What is Fluorescence?

Fluorescence, emission of electromagnetic radiation, usually visible light, caused by excitation of atoms in a material, which then reemit almost immediately (within about 10−8 seconds).

What is meant by fluorescence quenching?

Fluorescence quenching refers to any process that decreases the fluorescence intensity of a sample. A variety of molecular interactions can result in quenching. These include excited-state reactions, molecular rearrangements, energy transfer, ground-state complex formation, and colli-sional quenching.

How to Calculate Fluorescence Rate Constant?

Fluorescence Rate Constant calculator uses Rate Constant of Fluoroscence = Rate of Fluoroscence/Singlet State Concentration to calculate the Rate Constant of Fluoroscence, Fluorescence Rate Constant formula is defined as the rate constant of the rate equation for at which spontaneous emission occurs. It can emit a photon and in the process get converted back to the ground state. This is fluorescence and the fluorescence decay process is a first-order rate process with a rate constant denoted by kf. Rate Constant of Fluoroscence is denoted by K_f symbol.

How to calculate Fluorescence Rate Constant using this online calculator? To use this online calculator for Fluorescence Rate Constant, enter Rate of Fluoroscence (R_f) & Singlet State Concentration ([M_S1]) and hit the calculate button. Here is how the Fluorescence Rate Constant calculation can be explained with given input values -> 750 = 15/0.02.
