We found that without electric field the CL emission maximum is in the blue-green region for a PDPV-ZnO:Mg composite deposited on Si-SiO2 substrate with gold electrodes. Application of positive bias suppressed the blue-green emission and shifted the emission maximum to the red region. The mechanism for the formation of the exited states in PDPV-ZnO:Mg structure implies the presence of radiative recombination channels, which can be controlled by an electric field.
