Glow stick - Wikipedia
The glow stick contains two chemicals, a base catalyst, and a suitable dye (sensitizer, or fluorophor). This creates an exergonic reaction. The chemicals inside the plastic tube are a mixture of the dye, the base catalyst, and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide.
What are glow sticks, and what’s the chemical reaction that …
Oct 19, 2021 · Glow sticks light up when oxalate esters react with hydrogen peroxide to form a high-energy intermediate (possibly 1,2-dioxetanedione). This intermediate reacts with dye, which moves to an excited state (indicated with *) and then releases light as it relaxes.
The Chemistry Behind Glowsticks - ThoughtCo
Oct 16, 2019 · The basic premise of the reaction is that the reaction between the two chemicals releases enough energy to excite the electrons in the fluorescent dye. This causes the electrons to jump to a higher energy level and then fall back down and release light.

Jun 2, 2018 · A glow stick is an example of chemiluminescence. This means luminescence or light is produced as the result of a chemical reaction. Several factors affect the rate of a chemical reaction, including temperature, concentration of reactants, and the presence of other chemicals.
How Light Sticks Work - HowStuffWorks
Nov 22, 2023 · The chemical reaction in a glow stick usually involves several different steps. A typical commercial light stick holds a hydrogen peroxide solution, a solution containing a phenyl oxalate ester and a fluorescent dye.
The Chemistry of Glow Sticks - Compound Interest
Oct 14, 2014 · The action of snapping the glow stick breaks the glass cylinder, allowing the two solutions to mix and kicking of the reaction leading to the glow. The reaction that takes place is between the hydrogen peroxide solution and the diphenyl oxalate.
What is chemiluminescence? – Science in School
May 25, 2011 · Chemiluminescence reactions, such as those in glow sticks, are temperature-dependent. The reaction speeds up as the temperature rises – snapping your glow stick in hot water will produce a fantastic glow, but it will not last as long as it would at room temperature.
In Chemiluminescence, two molecules react together to create a third excited intermediate molecule. This molecule finally relaxes back to the ground state with the release of a photon of light at a frequency, which we can see in the visible range of the electromagnetic spectrum.

Oct 31, 2016 · Some chemical reactions—like those happening inside glow sticks—give off light. This process is called chemiluminescence (ke-mee-loo-mih-NEH-sens). A glow stick is made of a flexible, transparent plastic tube filled with a dye solution, a …
How do glowsticks work? | Science Questions - The Naked Scientists
Nov 6, 2005 · In a glowstick, the chemical reaction that energises the luminol is usually the oxidation of an ester, called phenyl oxalate, by hydrogen peroxide (H2O2) in the presence of a strong alkali, like sodium hydroxide (NaOH).
