ABSTRACT:
A donor element adapted for use in making an OLED device including a donor support element; a light-absorbing layer disposed over the donor support element, which in response to light, produces heat; a host material layer disposed over the light-absorbing layer; and a dopant layer disposed over the host material layer such that when the donor element is placed 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 of host materials and dopant materials from the light-absorbing layer to cause at least partial mixing in the OLED device.
