摘要: Abstract Compounds of Sr4Al14O25: Eu were prepared in air atmosphere by high temperature solid state reaction. The reduction Eu3+→Eu2+ was firstly observed the aluminate phosphor synthesized condition. This made a new family and Sr4Al14O25 member compounds which Eu3+ ion could be reduced to Eu2+ form when fired atmosphere. explained means charge compensation model. Experiments based on model designed carried out, results supported this
