  • A new green phosphor, ($Mg_{1-x-yZnx)$)$Al_2O_4:Mn^{2+}{_y}$ (0 x 0.6, 0.001 y 0.01), was synthesized by a flux-assisted solid reaction and its vacuum ultraviolet (VUV) excitation and emission characteristics were examined in this study. The chromaticity and peak intensity of the $(Mg_{0.79}Zn_{0.2})Al_2O_4:Mn^{2+}{_{0.01}}$ (x = 0.177, y = 0.745) phosphor were found to be more desirable than that of $Zn_2SiO_4:Mn^{2+}$ (x = 0.216, y = 0.72) phosphor as a green primary color.

  • This paper presents the effects of the phosphor layer morphology related to the discharge volume on the discharge and radiation characteristics of the Red, Green, and Blue cells in an AC-PDP. As the thickness of the phosphor layer increases and the corresponding discharge volume in the cells decreases, the voltage margin decreases due to an increase in the sustain voltage. In contrast, the IR(Infrared) emission, discharge current, and luminance characteristics remain almost unchanged, regardless of any changes in the phosphor layer morphology.

  • The $Zn_2SiO_4:Mn$ phosphors were prepared using polymer matrix technique in order to improve the performance of green emitting phosphors for plasma display panel(PDP). $Zn_2SiO_4:Mn$ phosphor exhibits a strong green emission around 520-530 nm. The emission intensity and particle size of powders were controlled by sintering temperature and raw material composition. The zinc silicate $Zn_2SiO_4:Mn$ single phase were obtained at lower temperature than prepared by solid-state reaction method. PL luminance of $Zn_2SiO_4:Mn$ phosphor was similar to the commercial material.

  • Inside of working PDP, there exist highly reactive conditions in the gap between two glass panels. MgO layer and phosphor have been investigated as a function of discharge and temperature. A drastic reduction in carbon impurity was observed on the surfaces after discharging and heat treatment. Carbon composition on the MgO and phosphor is a dominant factor for their instability

  • Main PDP panel efficacy improvement factors are discussed. A large panel efficacy improvement can be obtained through a combination of discharge efficiency improvement and phosphor improvement. Important design elements are a high Xe-content gas mixture, the application of a $TiO_2-layer$, and a new green phosphor with little saturation at high VUV-load. In a 4-inch color test panel with a conventional stripe-type cell configuration a white efficacy of 4.4 lm/W and a luminance of 5000 $cd/m^2$ is obtained for sustaining at 250V in addressed condition.

  • In this study, the luminance, luminous efficiency and address time of an PDP as a parameter of the phosphor thickness and the size of discharge space are investigated. The maximum luminance and luminous efficiency are obtained at the phosphor thickness of 30 ${\mu}{\textrm}{m}$ for the rib height of 110 ${\mu}{\textrm}{m}$. For the rib height of 120~160 ${\mu}{\textrm}{m}$, the maximum values are obtained at the thickness of 50 ${\mu}{\textrm}{m}$ regardless of the kind of R, G and B phosphor. These results do not affected by the variation of discharge space. The average decrease rate of the total charge to the phosphor thickness is about 3.35pc/cell/10 ${\mu}{\textrm}{m}$ and the average increase rate of the addressing time is about 0.027 $mutextrm{s}$/10 ${\mu}{\textrm}{m}$.

  • An new green phosphor, $(Y,Gd)Al_3(BO_3)_4$:Tb was synthesized by flux assisted solid reaction and its VUV excitation and emission characteristics were examined. The luminance of $(Y,Gd)Al_3(BO_3)_4$:Tb at 147 nm excitation was higher than that of $YBO_3:Tb$, while keeping the spectra and decay time of Tb ion same as those of $YBO_3:Tb$.
