La chemiluminescenza

[Luminol's Spectra]

BASIC INFORMATION AND PHYSICAL PROPERTIES
In 1928, H. O. Albrecht [5] noticed that while combining a certain compound in an aqueous alkaline solution with hydrogen peroxide and a metal catalyst, the resulting solution produces a blue-green light at a wavelength of approximately 424 nm. This light emitted little or no heat and glowed at a decent intensity. He realized that he found a new chemiluminescent source which would have a positive impact on the chemistry world and beyond.
