Abstract
$Zn_2SiO_4$:Mn green phosphors doped with Ga for PDP were synthesized by solid state reaction method. Photoluminescence measurements showed a new emission peak at around 600 nm for $Zn_2SiO_4$:Mn phosphors doped with Ga. Also, the luminescent color with doping $Ga^{3+}$ in the $Zn_2SiO_4$:Mn phosphors changed to green from yellowish green. Consequently, the new peak and charge of the luminescent color in the $Zn_2SiO_4$:Mn, Ga phosphors were attributed to $^2E{\rightarrow}^6A_2$ transition of $Mn^{4+}$.
