Mr Letswalo performed the experiments which led UJ physics researchers to the discovery that it is possible to get double the light intensity in a common light-emitting material. If the material succeeds, LED lighting could be far more affordable. The research appears in Luminescence at https://doi.org/10.1016/j.jlumin.2021.118462
