The hot electron energy was obviously increased by inserting SiO
2
layers into the central part of the luminescent layer in the layered optimized TFEL devices. But the improvement of brightness and efficiency was dependent on the crystallinity of the active layer. The green emission intensity and efficiency of the sample with two active layers were higher than that of the one-active-layer sample
while they were decreased greatly in the 3-active-layer sample due to the poor quality of the active layer.
