By comparing the performances of newly devised devices as a function of the position of the LiF in the Alq(3) layer, the authors propose the optimal position of the LiF in the Alq(3) layer. Experimental results show that the efficiency and brightness of the newly devised device with LiF in the Alq(3) layer were seven times higher than that without LiF in the Alq(3) layer.
