The Shrinking Green Gap: Trends in Solid-State Green Emitters
Dec 7, 2018 — Human eyes are most sensitive to light in the yellow-green region of the visible spectrum. This well-known fact is a result of the way mammalian eyes, and for that matter the eyes of all land-dwelling animals, have evolved from those of aquatic creatures. Electromagnetic radiation falling in the visible spectrum passes relatively unattenuated through water, and animal eyes have evolved to take advantage of this situation. Our eyes see light spanning roughly the wavelength region from 400
