Formation of green-emitting LaPO4:Ce,Tbnanophosphor layer and its application to highly transparent plasma displays

Abstract

Uniformly sized LaPO4:Ce,Tb nanophosphors were produced by using lanthanide nitrates and phosphoric acid along with citric acid and polyvinylpyrrolidone (PVP). The most efficient nanophosphors were obtained by varying their post-annealing temperature and chemical composition. The optimized nanophosphors were subsequently dispersed in 2-methoxyethanol and a highly transparent green-emitting nanophosphor layer was formed on a glass substrate via spin-coating of the dispersion. The spin-coating was repeated up to 7 times to increase the thickness of the nanophosphor layer. Despite multiple coatings, all nanophosphor layers maintained an excellent visible transparency. Ultimately, using the nanophosphor layer deposited on glass substrate, mini-sized transparent plasma display panels (PDPs) were fabricated and their luminance characteristics were described.
