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