A donor element adapted for use in making an OLED device,nincludes a donor support substrate; a light-absorbing layer disposed over thensubstrate which, in response to light, produces heat; an emissive layer disposednover the light-absorbing layer; and a hole-transporting layer disposed over thenemissive layer such that when the donor element is positioned in a transfernrelationship with the OLED device and when light is absorbed by the light-absorbingnlayer, heat is produced that causes the vaporization transfer across angap, of hole-transporting materials and emissive materials to the OLED device. |
