The Joint Measurements of Electroluminescence and Photoluminescence of PET Films under Low Temperature
The EL intensity and the spectrum of the PET films were tested under the low temperature by home-made experimental set-up on the conditions of DC high electric fields and irradiated by xenon lamp. The result shows that there are emission peaks at about 350~450nm, 500~600nm and 750nm in the EL spectrum of the PET films. The intensity of light emission increases with the applied electric fields; the pre-breakdown field is about 3.3MV/cm, this threshold value is no significant change which compares with the normal temperature.
