Application of Neodymium Oxide into Transparent Dielectric Materials for PDP

For purer images in plasma display panel, a new dielectric compositions containing neodymium oxide were studied. In the present study, Pb-based compositions were used as mother glasses (PbO-$B_2O_3-SiO_2Nd_2O_3$) and thermal, dielectric, and optical properties were measured. As a result the new dielectric with a rare-earth oxide made selectively visible light penetrated and showed especially noticeable absorption properties at 585 nm that is surely related to the erroneous gas from Ne discharge. Thus, this light purple colored glass composition will help PDP to come true to get better imaging process.
