The EL emission spectra show that the brightness of the novel structure devices greatly increases compared with that of devices with traditional double insulator structure, and the ratio of blue emission to red emission of the novel structure device is also improved. The improvement of the EL characteristics of this kind TFEL device is attributed to both of the electron acceleration and the ZnS/SiO 2 interface.展开更多
A new TFEL material ZnS X O 1-X : Ce 3+ is prepared. The EL brightness of ZnS X O 1-X : Ce 3+ is at least one order higher than that of ZnS: Ce 3+ at the same doping concentration of Ce 3+ .

The EL brightness of ZnS X O 1-X : Ce 3+ is at least one order higher than that of ZnS: Ce 3+ at the same doping concentration of Ce 3+ . The EL emission wavelength of ZnS X O 1-X : Ce 3+ (\%X\%=0.5) ranges from 400 to 600 nm. The emission of ZnS X O 1-X : Ce 3+ may be used as the blue part of white TFEL.展开更多
