ORGANIC MATERIALS FOR AN EVAPORATION SOURCE

摘要

A method of using a compacted pellet having uniform blended mixture with at least first and second different organic components that sublime at temperatures T<SUB>1</SUB> and T<SUB>2</SUB> respectively, wherein T<SUB>1</SUB> represents the temperature of the first organic material with the lowest sublimation temperature and T<SUB>2</SUB> represents the temperature of the second organic material with the highest sublimation temperature, to form an organic layer having a uniform blended mixture of the organic components, includes providing a compacted pellet, having a top and bottom surface, into a boat having an open top surface wherein the compacted pellet conforms to the interior of the boat; and applying heat to the top of the compacted pellet to cause the deposition of a uniform blended mixture of the organic components to form an organic layer.
