heres how it works, its reversed because this is the method to detect blood from a crime scene but it makes sense

luminol powder (C8H7O3N3) is mixed with hydrogen peroxide (H2O2) and a hydroxide (e.g., KOH) in a spray bottle. The luminol solution is sprayed where blood might be found. The iron from the hemoglobin in the blood serves as a catalyst for the chemiluminescence reaction that causes luminol to glow, so a blue glow is produced when the solution is sprayed where there is blood

lamp ***** >luminol stock solution (2 g luminol + 15 g potassium hydroxide + 250 mL water)

3% hydrogen peroxide in water (common over-the-counter concentration)

there you go guys

I didn't know the technical side, but I knew the gist of it. Forensics class ftw. Thanks anon.
