Paper Abstract

In order to combine both advantages of organic and inorganic materials and to solve the problem of mobility mismatch between hole transport layer (e.g. NPB) and electron transport layer (e.g. AlQ) of organic light emitting diodes, a mobility-tunable HTL of silicon-rich silicon oxide (Si1+xO2) is proposed. By changing the degree of excess silicon x, the mobility of Si1+xO2 can be controlled into a suitable range of ~10-5 cm2·V-1·s-1 which matches well with that of AlQ. The organic light emitting devices fabricated on silicon substrates have a lower operating voltage of 6.0 V and a higher maximum power efficiency of 0.33 lm/W.
