Title: Co-deposition methods for the fabrication of organic optoelectronic devices

Patent ·
OSTI ID:1321864

A method for fabricating an OLED by preparing phosphorescent metal complexes in situ is provided. In particular, the method simultaneously synthesizes and deposits copper (I) complexes in an organic light emitting device. Devices comprising such complexes may provide improved photoluminescent and electroluminescent properties.
