Efficiency enhancement of a dielectric barrier plasma discharge by dielectric barrier optimization

“…MgO possesses a high secondary electron emission coefficient and is therefore the most widely used surface protective layer in plasma displays. 11,12 There are also attempts to produce high density plasma by using further metal oxides. Ohtsu et al 13 tested MgO, SrTiO 3 , CuO, and TiO 2 as metal oxide electrodes in a capacitive coupled plasma.…”

Role of surface and bulk plasmon decay in secondary electron emission

“…5 SE emission also plays a crucial role in the energy and charge balance of gaseous electronics such as plasma display panels. 6,7 Progress in the fields addressed above hinges on an improved understanding of the SE emission mechanism, which can then be taken into account in the modeling of these phenomena. Unfortunately, SE emission is still far from being quantitatively understood, and experimental data for the SE yield exhibit a large scatter in some cases exceeding a factor of 7.…”

Secondary electron emission and glow discharge properties of 12CaO·7Al2O3electride for fluorescent lamp applications

“…For example, it has been known that the luminous efficiency is improved by changing the cathode material from Ni to Mo, as a result of the reduction in the cathode fall voltage. Improvement was also achieved by depositing a film of doped diamond or MgO on the surface of a metal electrode, thereby lowering the electron emission threshold [30][31][32][33][34][35][36][37][38][39], although the lifetime of the lamp was not satisfactory.…”
