Method for depositing a target material onto a organic electrically functional material
Abstract:
The invention relates to a method for depositing a target material onto an organic electrically functional material. The method includes the steps of: providing a substrate with an organic electrically functional material, like an emissive electroluminescent layer; creating a vapor plume of target material by pulsed laser deposition; depositing a first layer of target material on the organic electrically functional material, while maintaining the maximum particle velocity of the deposited particles below a preset value; and depositing a second layer of target material on the first layer of target material, while the maximum particle velocity of the deposited particles is above the preset value. The invention also relates to an intermediate product and to an organic light emitting diode.
