Organic Electroluminescence Using TPD as the Emitting Layer

摘要

Organic electroluminescent thin film using TPD as an emitting layer with structure of Glass/ITO/TPD/Al is fabricated. Its V-I curve, V-B curve and electroluminescent spectra are measured and analysed.The blue emission with luminance of 0.74 cd/m 2 and luminous efficiency of 1.35×10 -3 lm/W is achieved at DC voltage of 24 V.
