Abstract
In an attempt to improve the luminance efficiency of PDP, discharge cells of the PDP were prepared using mono-dispersed ceramic powders. The powders used were either mono-dispersed SiO2 or TiO2 coated SiO2 powders. The powders were prepared through hydrolysis and condensation reactions of silicon alkoxides in the presence of ammonia and its polydispersity was less than 5%. A slurry dispersed with those powders were infiltrated through the channels of barrier ribs morphology and the solvent was evaporated in a controlled manner to form a superlattice structure of FCC. Using those cells formed, the luminance efficiency of the cells was measured and compared with conventional cells. In addition, the effect of a thin layer of TiO2 coating on the surface of the crystals on the luminance efficiency was examined. The results indicated that the application of photonic band gap materials on the barrier ribs improves the luminance efficiency significantly.
