How does fluorescence work?
Fluorescent molecules
At the heart of fluorescence lies fluorescent molecules, also known as fluorophores. These molecules possess specific chemical properties that enable them to absorb light energy and re-emit it at longer wavelengths. The structure and composition of the molecule determine its fluorescence properties, including its absorption and emission spectra.
Absorption and emission
When fluorescent molecules are exposed to light, they absorb photons, gaining energy in the process. This absorption causes the electrons within the molecules to move to a higher energy state. Subsequently, these excited electrons release the absorbed energy in the form of photons, emitting light at specific wavelengths. The emitted light is often of a different color than the absorbed light, resulting in the characteristic fluorescent glow.
Stokes shift
One crucial concept in fluorescence is the Stokes shift. This phenomenon refers to the difference between the wavelengths of absorbed and emitted light. In fluorescent molecules, the emitted light has a longer wavelength than the absorbed light, resulting in a shift towards the red or infrared region of the electromagnetic spectrum. The magnitude of the Stokes shift depends on the specific fluorophore and its molecular structure.
Types of fluorescent paint
Standard fluorescent paint
Standard fluorescent paint refers to the traditional type of fluorescent paint that produces a vibrant, glowing effect under various lighting conditions. It is formulated to emit light in the visible range, typically in shades of green, yellow, orange, and pink. Standard fluorescent paint finds applications in safety signage, artistic projects, and decorative purposes where visibility and enhanced aesthetics are desired.
Ultraviolet (UV) fluorescent paint
In contrast to standard fluorescent paint, UV fluorescent paint interacts specifically with ultraviolet light. It absorbs UV light and emits visible light, resulting in an intense glow. UV fluorescent paint is widely used in special effects, art installations, and club lighting, creating an otherworldly or psychedelic atmosphere.
