By using electropolymerized poly(N-vinylcarbazole) (PVCz) as a hole injecting film on porous n-silicon (PS), an all-solid state multicolor EL device on the basis of PS was able to be fabricated. The electroluminescence (EL) from the PVCz/PS device under forward bias was enhanced as compared with the device without PVCz film. An EL peak-shift of this device was observed with an increase in applied forward bias.
