| Abstract: | The new complex of Eu(BA)_2(MAA)(Phen) is synthesized and is used as a red light-emitting material in our organic electroluminescent devices with the structure of ITO/TPD/Eu(BA)_2(MAA)(Phen).The brightness of 15 cd/m~2 and luminous efficiency of 0.25 lm/W are achieved at the voltage of 26 V. This material has strong photoluminescence and relatively good electroluminescence along with excellent mono-chromaticity.The mechanism of this EL device is discussed. |
