Rare red green blue to light up the dark (VIDEO)
Caption
UJ physics researchers discover they can get double the light intensity in a common light-emitting material. If the material succeeds, electric lighting bills could be much lower for everyone. The research appears in Luminescence at https://doi.org/10.1016/j.jlumin.2021.118462
