Bright new light from old material: Zinc Oxide + PVA
Scientists have long known that Zinc Oxide (ZnO) is a useful material — it’s cheap, abundant, and has been used in everything from electronics to sunscreens. But ZnO’s natural glow is mostly in ultraviolet (UV), which isn’t helpful for everyday lighting. SpringerLink+1
A recent study, that included MSE Professor Dr. Luiz Jacobsohn, took a fresh approach: they grew ZnO nanoparticles inside a simple polymer medium, Poly(vinyl alcohol) (PVA)....
