Disclosed herein is a method for producing an amorphous aluminum nitride layer having a desired stoichiometry. Such method involves the steps of disposing a substrate in close proximity to an aluminum target in a low pressure atmosphere of nitrogen and an inert gas, and reactive sputtering an aluminum nitride layer onto the substrate at a certain minimum deposition rate while maintaining certain parameters (i.e. nitrogen-to-inert gas ratio, substrate temperature, sputtering power, nitrogen flow rate and sputtering pressure) within certain limits.

摘要:
Certain example embodiments relate to organic light emitting diode (OLED)/polymer light emitting diode (PLED) devices, and/or methods of making the same. A first transparent conductive coating (TCC) layer is disposed, directly or indirectly, on a glass substrate. An outermost major surface of the TCC layer is planarized by exposing the outermost major surface thereof to an ion beam. Following said planarizing, the first TCC layer has an arithmetic mean value RMS roughness (Ra) of less than 1.5 nm. A hole transporting layer (HTL) and an electron transporting and emitting layer (ETL) are disposed, directly or indirectly, on the planarized outermost major surface of the first TCC layer. A second TCC layer is disposed, directly or indirectly, on the HTL and the ETL. One or both TCC layers may include ITO. The substrate and/or an optional optical out-coupling layer stack system may be planarized using an ion beam.
摘要:
A method for selecting two different light-emitting materials for use in an OLED device, each of which produces different color light, which combine to produce white light. Each light emitting material has its own point on a chromaticity diagram, and the light-emitting materials are selected such that, when a line is drawn between the first point and the second point, it passes through a desired white area defined on a chromaticity diagram.
