- Abstract
- Transparent plasma display can be realized by developing the synthetic chemistry of appropriate nanophosphors and generating nanophosphor-based transparent luminescent layers. For this goal, red-emitting Y(V0.5, P0.5)O4:Eu nanophosphors were synthesized by a facile hydrothermal route at 200°C for 48 h and the resulting nanophosphors were subsequently annealed at 800°C at an ambient atmosphere. The crystallographic structure, morphology, and emission property of the as-synthesized and annealed nanophosphors were compared. Choosing 2-methoxyethanol as a dispersion medium and applying a standard sonication, well-dispersed nanophosphor solutions could be prepared. Using these dispersions, visible transparent nanophosphor layers were spin-deposited on glass substrates. By combining Y(V0.5, P0.5)O 4:Eu nanophosphor layer/glass substrate as a rear plate with a front plate used in a conventional plasma display panels (PDPs), mini-sized transparent red-emitting PDPs were constructed. Transmittance and luminance properties of two transparent test panels using as-synthesized versus 800°C-annealed nanophosphors were characterized and compared.
