Abstract: Provided by the invention is a novel synthetic inorganic triboluminescent material in the form of a powder, sintered block or thin film, of which the matrix phase is a piezoelectric crystalline material of a wurtzite structure such as zinc sulfide and the activator to serve as the center of luminescence is a transition metal element such as manganese, copper and rare earth elements in an amount of 0.01 to 10% by weight. The triboluminescent material is prepared by subjecting a powder blend of the matrix phase material and a thermally decomposable compound of the activator element first to a preparatory calcination treatment at 500 to 800.degree. C. and then, preferably in the form of a powder compact, to a second calcination treatment at 900 to 1700.degree. C., preferably, in vacuum under a sealed condition, when the material is liable to cause sublimation, or in an atmosphere of a reducing gas. The thus obtained triboluminescent material can be used as a source material for the formation of a thin film on a substrate, for example, by ion plating. The efficiency of the triboluminescence is increased by increasing the crystallinity of the material by controlling the conditions of film deposition and/or by undertaking a heat treatment of the thin film as deposited.

Abstract: A plasma display panel having its thermal degradation and VUV deterioration reduced through enhancement of the crystallinity of luminant excitable with vacuum ultraviolet radiation to thereby attain an enhancement of luminous efficiency; and a process for producing the same. The plasma display panel comprises a pair of opposite arranged substrates and, interposed therebetween, a phosphor layer that is excited with vacuum ultraviolet radiation to thereby emit light, the phosphor layer containing spherical fine particles of a luminant excitable with vacuum ultraviolet radiation. The luminant is composed only of a matrix substance and an activator and is highly pure without having any impurity phase. Accordingly, the phosphor layer can be formed while maintaining the luminance of luminant excitable with vacuum ultraviolet radiation, so that the luminescence intensity of phosphor layer can be enhanced. Thus, there can be provided a plasma display of high luminance.
