It is used to find fingerprints and blood on porous surfaces.Lewkowicz Aneta Baranowska Karolina Bojarski Piotr Józefowicz Marek 2019 Solvent dependent spectroscopic properties of fingerprint reagent - 1,8-Diazafluoren-9-one https://linkinghub.elsevier.com/retrieve/pii/S0167732219313479 Journal of Molecular Liquids en 285 754–765 10.1016/j.molliq.2019.04.110 149852434 subscription It makes fingerprints glow when they are lit by blue-green light. DFO reacts with amino acids present in the fingerprint to form highly fluorescent derivatives. Excitation with light at ~470 nm results in emission at ~570 nm.Pounds C.
