APPLICATION OF CdS TO MULTILAYER TFEL DEVICES
CdS在多层薄膜电致发光器件中的新应用

Q-V charater of the samples containing CdS is compared with that of the samples not containing. The transfer charge of the samples with CdS is more larger than that of the samples without CdS.This indecates that CdS can provide more electrons. But during these electrons transfer into ZnS layer, the energy is reduced. When these electrons are accelerated by SiO2, the luminescent intensity increases 2.5 times in orders. When the samples with CdS gets the maximum luminescent intensity, the samples without CdS just starts to emite at the same voltage. ms indicates that the lumineseence of the samples with CdS is due to the electrons from CdS.
