Efficient blue light organic electroluminescent (EL) devices were fabricated by using a highly fluorescent bis(2-(2-hydroxyphenyl)-pyridine)beryllium(Bepp

) as an emitting layer. The multiplayer devices
a Bepp

emitting layer
and an electron transport layer were employed in order to obtain high performance. For the devices
the maximum luminance of 6200cd/m

and electroluminascent efficiency of 1.3cd/A(0.71lm/W) were achieved. The EL spectrum peak of Bepp
