(Y,Gd)BO[sub 3]:Eu[sup 3+] and Y(V,P)O[sub 4]:Eu[sup 3+] Thin-Film Phosphors for Use in Transparent Plasma Display Panels

and thin-film phosphors were deposited on conventional and corrugated substrates to test their applicability for use in transparent plasma display panels (PDPs). The exact target structure and stoichiometry of and transferred well to the single-phase film by optimizing the deposition conditions. The corrugated substrates consisting of nanorod-type two-dimensional photonic crystal layers enhanced the photoluminescence efficiency, albeit at the expense of transparency. We employed the fact that conventional PDPs would adopt a mixture powder of and as a compromise between luminance and color chromaticity. To achieve this compromise in a thin-film state, we prepared a sandwich-type thin film using and phosphors.
