three organic thin film electroluminescence (OTFEL) cells with different thickness of luminescent layer:300Å
600Å
1500Å
were prepared. The OTFEL cells were the structure of single layer
and the 8-hydroxyquinoline aluminum was used as a luminescent layer. Comparing and analysising their properties of
I-V
and
B-I
it is conformed that the thickness of luminescent layer drastically influences the brightness of OTFEL cells. The cause were discussed by transport processes of electrons and holes in luminescent layer under DC current.
