Electroluminescent laminates having a thin film electroluminescent oxide phosphor layer on insulating substrates. Thin film EL laminates are produced using high dielectric constant layers, such as SrTiO3 and BaTiO3 next to the oxide phosphor layer on one or both sides of the oxide layer, primarily as...http://www.google.es/patents/US6403204?utm_source=gb-gplus-sharePatente US6403204 - Oxide phosphor electroluminescent laminate
