Fluorescence and luminescence are chemical phenomena that have some similarities, but there are also important differences between them.
The difference between Fluorescence And Luminescence is that fluorescence refers to the emission of light from a material after it has been excited by the absorption of electromagnetic radiation, such as ultraviolet light.
On the other hand, Luminescence refers to the emission of light by a material without having to be excited by the absorption of previous electromagnetic radiation.
Difference Between Fluorescence and Luminescence in Tabular Form

Luminescence |
| Emission of light by a material after being excited by the absorption of electromagnetic radiation. | Emission of light by a material without the need to be excited by the absorption of previous electromagnetic radiation. |
| The emitted light is of a specific wavelength and is less than the wavelength of the electromagnetic radiation that is absorbed. | The emitted light can have different wavelengths and can be of a wavelength greater than or equal to the electromagnetic radiation that is absorbed. |
| The emitted light dies off quickly after the exciting electromagnetic radiation is no longer present. | The emitted light can last long after the exciting electromagnetic radiation is no longer present. |
| Fluorescence occurs in a limited number of materials, such as certain pigments and organic molecules. | Luminescence occurs in a wider variety of materials, including certain minerals and some biological organisms. |
What is Fluorescence?
Fluorescence is a chemical phenomenon in which a material emits light after being excited by absorbing electromagnetic radiation such as ultraviolet light.
The light emitted by fluorescence has a specific wavelength and is smaller than the wavelength of the electromagnetic radiation absorbed.
Where it is occurred?
Fluorescence occurs in a limited number of materials, such as some pigments and organic molecules.
Fluorescence is often used in practical applications such as lighting, chemical identification and radiation detection.
Applications of Fluorescence:
Furthermore, fluorescence is also widely studied in scientific research due to its interest from a chemical and biological point of view.
What is Luminescence?
Luminescence is a chemical phenomenon in which a material emits light without the need for excitation by absorbing the previous electromagnetic radiation.
The light emitted by luminescence can have various wavelengths and can have a wavelength greater than or equal to the wavelength of the absorbed electromagnetic radiation.
Where it is occurred?
Luminescence occurs in a wide variety of materials, including some minerals and some biological organisms.
Although luminescence is less used in practical applications, it is widely studied in scientific research due to its chemical and biological interest.
Applications of Luminescence:
Some practical applications of luminescence include measuring pH in solutions and detecting certain diseases.
