Summary:1 2 1 2 A method of using a compacted pellet having uniform blended mixture with at least first and second different organic components that sublime at temperatures Tand Trespectively, wherein Trepresents the temperature of the first organic material with the lowest sublimation temperature and Trepresents 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.
