How do Artemis pigments work? What is photoluminescence?
Most pigments just (i) absorb certain light wavelengths and (ii) reflect others, but our fluorescent and phosphorescent pigments also (iii) absorb certain wavelengths and re-emit that light energy at different wavelengths. That is, they use energy from the photons in lightwaves to achieve a glow or “luminescence.” Thus, they are “photoluminescent.” Normal pigments are “passive.” Because of (iii) above, our pigments are considered “active.
