【gmtlight news】Can the fluorescent rod emit light after chemical reaction? Let's see what Mr. Wang Li, an expert in gmtlight's sales of fluorescent rods, What he tells us.
We know that when the fluorescent rod is broken, it will start to glow. Is this light fluorescent? Actually, it's not. It's a chemical reaction, an energy conversion. That is to say, the fluorescent rod produces chemiluminescence, and the energy of photons comes from chemical reaction.
There is a closed glass tube inside the fluorescent rod, which is sealed with a chemical material. The most external part of the fluorescent rod is a closed plastic tube, which has a chemical material between the glass tube and the plastic tube. During the storage process, they are isolated and do not undergo mixed reactions. When used, bending the fluorescent rod, the inner glass tube is broken, the reactants are mixed together, and the chemiluminescent reaction begins.
Hydrogen peroxide and diphenyl oxalate are the main components in the chemical reaction of fluorescent rods. Simply put, this reaction produces a "high-energy" intermediate product, which does not emit light itself, but can transfer energy to fluorescent dyes, exciting dyes into the luminous state.
This is the basic principle of chemical reaction in fluorescent rods. The specific color of light emitted depends on which fluorescent dye is used.
The chemical reaction takes 4-8 hours to complete, then the chemiluminescence can not be maintained, so the fluorescent rods are disposable.
We want to emphasize that there are still fluorescent dyes in the finished fluorescent rods. If the fluorescent dyes are excited by ultraviolet light, they can still give out real fluorescence.
You can try it.
