Improving Ramp-Discharge Characteristics by Using New Green Phosphor.

Optical Properties of Co3O4‐Doped ZnO–B2O3–SiO2–Al2O3 Glass System for a Transparent Dielectric Layer

“…Therefore, blue luminance needs to be relatively higher than green and red luminance in order to improve the color temperature of the PDP. There have been many approaches to improve color temperature, such as optimization of the color filter, the design of the driving scheme, asymmetric pixels, and new materials including phosphor, protecting layer, dielectric layer, and the barrier rib 4–7 …”

“…There have been many approaches to improve color temperature, such as optimization of the color filter, the design of the driving scheme, asymmetric pixels, and new materials including phosphor, protecting layer, dielectric layer, and the barrier rib. [4][5][6][7] Recently, control of the yellowing phenomenon in the transparent dielectric layer was investigated from a point of view that enhanced the color temperature in the PDP. These research results show that the formation of nanoparticles of Ag between the electrode and the dielectric layer can be restrained by transition metal ions such as Cu, Ce, and Co.…”

Luminescent properties of Tb‐activated rare‐earth oxyapatite silicate MLn 4 Si 3 O 13 (M = Ca, Sr, Ln = La, Gd)

“…In addition, the ZSM phosphor layer in PDPs have poor surface charge when the voltage is applied, resulting in reducing the margin of address voltage in comparison to red and blue phosphors. [3] To overcome the problems as mentioned above, we employ rare-earth oxyapatite MLn 4 Si 3 O 13 (M=Ca, Sr, Ba Ln=La, Gd) [4] as a host material. Tb-doped MLn 4 Si 3 O 13 phosphors have advantages as follows, (i) an efficient absorption band due to the 5d-band or charge transfer state of La (or Gd) for VUV radiation from Xe 2 excimer, (ii) shorter fluorescence decay time of the 4f intra-shell transition in comparison to the 3d intra-shell transition.…”

Effect of single crystalline MgO powder treatment of phosphor surface on discharge property of high-Xe AC plasma display panels

“…Much research on phosphors has focused on developing a new material or a method of surface treatment to improve the lifetime of phosphors or to compensate for the electro-negativity of green phosphor [6][7][8][9]. Some research has tried to improve the secondary electron emission coefficient c p of phosphors by mixing or coating them with MgO [10,11].…”
