title: Secondary electron emission and glow discharge properties of 12CaO·7Al2O3electride for fluorescent lamp applications.
abstract: 12CaO·7Al2O3electride, a sub-nanoporous compound having a work function of 2.4 eV, was examined as a candidate cathode material in fluorescent lamps. The electron emission yield was higher and the discharge voltage was lower for 12CaO·7Al2O3than for existing cathode materials such as Ni, Mo or W; therefore, the energy consumption of the fluorescent lamps can be improved using 12CaO·7Al2O3cathodes. Prototype glow-discharge lamps using 12CaO·7Al2O3were constructed and exhibited reasonable durability.
