Development of zeolite-derived novel aluminosilicate phosphors

► Zeolite-derived aluminosilicate phosphors were synthesized through the ion exchange route. ► Luminescence properties as a function of the Eu content were precisely studied. ► The oxidation state of Eu ions is discussed in terms of the heat-treatment condition. ► Best performance as a red phosphor exhibited 10 wt% Eu content and 1500 °C heat-treatment condition.
