| 摘要 |
A method for evaporating a solid organic material by sublimation using an infrared guiding heater which minimizes temperature gradients in the bulk of the organic target. The bulk is heated to a temperature below the sublimation temperature of the target. A localized area of the target is sublimated by the infrared guiding heater while regulating the temperature of the bulk. The vapor is then deposited over, and condensed on, a substrate to form a solid organic layer.
