Abstract

Light emission has been observed when stressing polymer films with an AC voltage. Films of thicknesses between 25 and 100 μm were used in this study. The work was done using a low-density polyethylene of cable grade without additives. A semitransparent gold layer was sputtered. For the same setup no light could be detected under DC stress. The fact that the light is field-independent and decreases when the transmission of light through the gold layer is decreased by increasing the thickness, indicates that the polymer is involved in the light emission. If so, the bulk of the polymer material and/or the volume closest to the electrodes could be responsible
