Abstract:
The present invention is a method of producing an ultraviolet light emitting phosphor material. This method includes a step of heat-treating a composition containing zinc and oxygen as main components and at least one selected from the group consisting of aluminum, gallium and indium as a sub-component, in the presence of at least two coexisting substances selected from the group consisting of zinc oxide, gallium oxide and phosphorus oxide under a non-oxidizing atmosphere.
