Different colored glow is obtained in vials.
name: Make glow sticks using TCPO and fluorescent dye
Wear eye protection and lab gloves.
Avoid contact of hydrogen peroxide with skin.
Always follow general safety
recommendations. Please note that conducting chemistry
experiments you must comply with the relevant legal procedures in
TCPO reacts with hydrogen peroxide and produces an intermediate - 1,2-dioxetanedione. It decomposes to CO2 and excites a fluorophore. So the chemical reaction energy transfers to light emission energy of the excited fluorophore in these reactions.
The wavelength of the emitted light depends on the nature of the flurophore. Thus BPEA emits green light, rubrene - yellow, 9,10-diphenylanthracene - blue, rhodamine B - red.
There is no light emission without a fluorophore in this reaction.
Divanillyl oxalate, biphenyl oxalate also may be used as an energy source for fluorescence.
