Phosphorescence (in the common meaning of the term) seen by naked eye:

UV Type Color Intensity Observation Frequency
Long Wave (365nm): Yellowish White


Blue amber : strong blue fluorescence LW due to the presence of a polycyclic aromatic hydrocarbon known as Perylene. It is formed from the resin of the Hymenea Protera tree unlike other ambers which originate from conifers.

Main Activator(s) and spectrum:

Most Common Activator: Intrinsic organic material

Peaks in the spectrum (nm):

Broad band centered at 500 nm (+/-100nm half-width) / "waves" at 480, 513, 548 and 592nm
