A lot of people used it to glowFluorescent barAnd bend it around in your hand and shine in the dark of night. What the hell is that
The fluorescent principle of fluorescent rods
The fluorescent rod's luminous principle is to release the photons from a single atom after they are activated and to form a source of light. Unlike the light bulbs, which use heat to stimulate atoms, the fluorescent rods are associated with the chemical reaction of the chemical material within them。
There are three main types of chemicals in fluorescent rods: peroxides, ester compounds and fluorescent dyes. Chemical reaction of peroxides and ester compounds, where the energy released from this reaction is passed to fluorescent the fluorescent rod that we see in light dye molecules is that fluorescent dyes release energy in visible light (from high energy to more stable low energy), where chemistry can be converted to light。
The fluorescent rods that we see are a rod containing two liquid compounds, ester compounds - phenylpropylate and fluorescent dye - dye solution. Before it was activated, the two solutions were installed in two separate tubes. In the middle of them is a small glass bottle containing hydrogen peroxide solution known as the “activator”。
How can the fluorescent rod be activated
The outermost layer of the fluorescent rod is a plastic tube with peroxide in the glass tube. When the fluorescent rod bends, the glass pipe inside is broken, the two solutions are mixed, the chemical material meets, and the energy released during the chemical reaction is transmitted to the fluorescent dye, where the fluorescent rod begins to glow。
We see fluorescent rods that are very colourful, and these different colours of light can be seen in color because the fluorescent dyes are different。
Depending on the compounds used in the fluorescent rods, the chemical luminescences vary in duration, ranging from minutes to hours. If its solution is heated, the fluorescent rod will give rise to greater light, but for a short period of time. If you want the fluorescent rod to darken, you just have to cool it。
Is fluorescent rods harmful to humans
The fluorescent rods are mainly plastic packaging, and the chemical liquids in the fluorescent rods are surrounded by plastic, do not come into direct contact with the human body and therefore do not cause harm to the human body. And the light from the fluorescent rod is not the light from the dyes that is triggered by radiation, but the non-radiation light from the dyes that is triggered by chemical reactions and does not harm the human body。
But today, some people are trying to catch up with fashion by breaking their fluorescent rods and coating liquids on the skin surface, which can cause some damage to the human body, which could be even greater in the case of more vulnerable children. So it's safer to have it all in your hand。
