摘要：

The voltage-tunable EL was obtained upon cathodic bias of n-type PS in contact with aqueous solution containing the persulphate ion. The EL behavior as a function of the external voltage and time was investigated. The results suggest that the mechanisms of voltage-tunable EL of n-typt PS cannot easily be attributed to quantum confinement effect.
