The carbon nanotube (CNT) auxiliary layers are suggested to reduce the high driving voltage in ac plasma display panel (AC-PDP). The CNT layer, which was integrated on dielectric layer overlapping the PDP bus electrode, was formed by electrophoretic deposition without sheltering further plasma emission light. The effective CNT pretreatment, uniform and thickness distribution of CNTs in the layer result in the excellent field-emission properties of low turn-on field (1.7 V/\mu\hbox{m}), which was proved to effectively reduce the discharge voltage of display cell with A-type (CNT layer is at the middle of indium-tin-oxide electrode) in a series of discharge testing. The lowest sustain voltage for turning on the cells was reduced by 30-40 V. The FE-PDP theoretical model was proposed for explaining the testing results. © 2012 IEEE. Source

MgO crystals have been exposed to vacuum ultraviolet (VUV) radiation from a synchrotron, with energies up to 9 eV, and the emitted light, at wavelengths above 200 nm, was observed. It is concluded that bulk excitons, play an important role in the diffusion of energy inside MgO crystals, resulting in 5.85 eV (212 nm) emission from the MgO terraces of large (0.2-2m) MgO: F crystals. In the case of aliovalent impurity doping, then the bulk exciton energy is also transferred to the Vk centres and 5.3 eV (235 nm) light is emitted. Both fluorine and silicon doping appear to promote UV surface emission, acting similarly to an ns2 ion inside MgO, while strong scandium doping is killing the surface emission completely. The 212 nm surface UV emission and the 235 nm bulk UV emission can be excited only at the bandgap edge. Broadband visible light, centred around 400 nm, is also emitted. Contrary to the UV emission, this is not generated when excited at the bandgap edge; instead, we find that it is only excited at sub-bandgap energies, with a maximum at the 5C surface excitation energy of 5.71 eV (217 nm) for the MgO terraces. © 2013 IOP Publishing Ltd.

Developing high gamma protective layer for high Xe concentration gas discharge is one of the most important way to achieve low power consumption Plasma TV. We have developed Ca xMg 1-xO(CMO) film and related processes for high Xe content PDP. The 50 inch CMO panel shows more than 20% increase of luminous efficacy and about 10 Volts voltage reduction in minimum sustain voltage. Source

CaxMg1-xO(CMO) has a merit of generating high secondly electron emission in high Xe content which results in high luminous efficacy PDP. The easy formation of CaCO3 and MgCO3 in manufacture process is a big challenge to mass production. Both technique and cost issues associated to this technology is discussed. Source
