Photochromics
1.1 General introduction to photochromism. The term "photochromism" or "photochromic" is believed to originate from the Greek words φωτόϛ (photos) and χρῶμα (chroma), which mean light and color, respectively. The photochromism can thus be simply defined as the feature to undergo a reversible change of color induced by light [1].
