Why better LED bulbs could lower lighting bills (IMAGE)
Caption
LED light bulbs swept in a revolution in safe lighting. But many people still risk fire at home because the bulbs are expensive to manufacture. 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
