CaS: EuCl_3, SrS: CeCl_3 thin film electrolumininescent devices were prepared by electron beam evaporation technique. During the phosphor deposition the substrate was kept at a temperature of 350℃. The red(650nm) and blue(475nm) Light emission was observed and the emission brightness B was measured as the function of applied voltage V, frequency f and concentration of rare-earth dopants. The brightest emission for the CaS: EuCl_3 and SrS: CeCl_3 devices were obtained with the 0.1mol% concentation, respectively. The maximum brightness were 85fL and 150fL under 5KHz sinusoidal voltage excitation, respectively.

An Ac-type Plasma Display Panel (PDP) operating with Ne-Ar(0.1%) Penning mixture gas is fabicated. The characterics of the panel with electrodes covered with thin and thick dielectric layers are studied. The brightness of the Neon-orange light emitted by the panel measured as function of applied voltage and frequency. As an application, a graphic display system equipped with PDP showing still and moving pictures is made.
