Abstract
An luminescent composition comprises a mixture of two or more materials, emitting electromagnetic radiation when subject to stimuli, wherein the spectral emission is not calculable at a first approximation as the simple weighted sum of the spectral emissions of the materials independently subject to said stimuli. Especially advantageous compositions are achieved if the anionic matrix is an oxide and the doping anionic salt is a fluoride or vice versa.
