摘要： The invention aims to provide a phosphor thin film eliminating a need for filters, having a satisfactory color purity, suited for RGB in full-color EL displays, enabling to simplify the manufacture process of full-color EL panels, and offering the advantages of minimized variation of luminance, increased yields, and reduced manufacture cost, a method for preparing the same and an EL panel.
Such objects are achieved by a phosphor thin film formed of a matrix material comprising an oxysulfide consisting of at least one compound selected from rare earth thioaluminates, rare earth thiogallates and rare earth thioindates, in which oxygen is incorporated, the matrix material further containing an element serving as a luminescent center, a method for preparing the same, and an EL panel using the same.
