Abstract
ZnO has a wide band gap of 3.37eV at room temperature and has attracted some interest because it is considered a promising green light-emitting phosphor for low-voltage luminescence in flat panel displays such as vacuum fluorescent tube (VFDs) and field emission displays (FEDs). It has been increasingly requested to develop blue cathode phosphors with high-efficiency and low-cost. The blue emission luminescence can be expected in Mg-doped ZnO because the band gap increases under partial substitution of MgO for ZnO. In the present work, the fabrication for (Zn,Mg) O solid solution and the effect of Mg-doping on the photoluminescence were investigated.
