Artificial Intelligence methods have been employed in the search for solid-state phosphors with a high luminescence quantum yield. An Artificial Neural Network was used to investigate how luminescence efficiency can be linked to phosphor composition. The trained network was then coupled to a Genetic Algorithm whose role was to locate the global optimum composition in the search space. The compound Tb0.039Gd0.104Ce0.063Si0.401B0.393Od (where d indicates the stoichiometrically-required amount o...
